The explosion of online celebrity cuisine in the National People’s Congress canteen has raised the memory of taste buds to the level of cultural expression.

  "I finally got it ‘ Online celebrity ’ Youth League! " With pictures and click Send, a graduate student of Renmin University of China Law School wrote such a circle of friends and joined the big team of "punching in" in the campus canteen.

  On the eve of Tomb-Sweeping Day, the Youth League made by the dining hall in the North District of Renmin University was once again "on fire", with an average of 2,000 copies sold every day. On the Internet, netizens from inside and outside the school have forwarded and commented on relevant news, bluntly saying "I want to eat". On March 26th, the Logistics Group of the National People’s Congress also launched the Youth League Gift Set, which was sold online and offline.

  In fact, the Youth League is not the only "online celebrity cuisine" produced by the National People’s Congress canteen. Also famous are more than 10 kinds of food, such as pumpkin bread in the east dining hall, gift box for new year’s goods in the central dining hall, Shandong jujube steamed bread bigger than the face in the west dining hall, and Chongyang cake in the north dining hall.

  Why can university canteens keep making "explosive online celebrity dishes"? How are these "online celebrity dishes" cooked? What kind of sparks can be generated when the canteen tastes big data and the Internet?

  Online and offline "sense of participation"

  Many students of Renmin University know Wang Ruorong and Song Da Me.

  Off-line, Wang Ruorong is the director of the canteen in the North District of the National People’s Congress. At the peak of eating, I can always see him shuttling among the students to collect comments. Online, he is also a little-known "online celebrity". Since he opened the Weibo, he has frequently interacted with students to discuss what is delicious in the canteen. He has also published a book called "The Taste of the National People’s Congress".

  Originally, there was only an ordinary "big pot rice" on the first floor of the North District canteen. Wang Ruorong found that this could not meet the needs of students, and made up his mind to open a Jiangnan flavor window, focusing on crab yellow soup packets. Not long after, a student went to Weibo to leave a message, "Can we also do some youth groups?"

  The suggestion was quickly adopted. Wang Ruorong studied it several times with the chef of the canteen. Before Tomb-Sweeping Day last year, this kind of snacks with Jiangsu and Zhejiang flavor was launched on the first floor of the North District canteen and sold for more than 20 days. Because all of them are on-site packages and steaming, students waiting in line often have to stand at the gate of the canteen from the window.

  At present, this "online celebrity Youth League" has two kinds of fillings: egg yolk floss and pine nut bean paste. In order to ensure the quality, Wang Ruorong and the masters did not choose the egg yolk packed in vacuum in the market, but pulled the egg yolk from the salted duck eggs on the spot; In order to adjust the greasy bean paste, they added kumquat pieces and pine nuts to it, blending a sour and sweet smell.

  If the youth league’s "red-hot" is an accident, then this year, other foods in the National People’s Congress canteen, like the youth league, have been on fire one after another, which proves that this is not just an accident.

  Song Da-i, also a "Weibo red man", was the deputy director of the Institute of Investigation Technology of the National People’s Congress. The associate professor of Renmin University commented that he "loves food and life". After being transferred from the front line of teaching to the general manager of the school logistics group, he began to "toss".

  "Warm People’s Congress" is the official WeChat of the logistics of the National People’s Congress, and it is also the WeChat WeChat official account that the students of the National People’s Congress pay the most attention to. In order to improve the service ability of the canteen, they posted a lot of news about campus food, such as new dishes and scheduled tasting activities.

  Not long ago, the logistics group also launched the "canteen iron powder group" on the micro-signal. Students of the Iron Powder Group can deeply participate in the promotion of new dishes in the canteen, the promotion of dishes and the tasting of dishes, and at the same time enjoy VIP treatment and participate in cooking demonstration classes and practical classes. The Logistics Group also gives lectures on cooking techniques to Iron Powder from time to time and gives live demonstrations on cooking. Carry out cooking practice classes or organize "iron powder" for cooking skill competitions.

  The opinions of these students can influence the standard of food in the canteen. Song Da I hope that the students who join are not "canteen tourists" who have tasted it, but "senior foodies" who really have an insightful understanding of the canteen. Their screening criteria for "iron powder" are: participating in 8 campus food activities each semester, and at the same time "punching in" and collecting 18 "likes" in the circle of friends.

  "Many times, food is just a chat." Song Dawei said that the canteen and students should break the distance and communicate more through various channels. Now, they display new products in articles pushed by WeChat, and also disclose the production process of "online celebrity cuisine" one by one.

  Song Da I gradually found that many students would "like" the canteen even if they didn’t eat new food. The alumni who have graduated seem to feel the happiness brought by the campus canteen from a distance, and many outsiders know the "online celebrity cuisine" of the National People’s Congress through this window.

  The "assembly line" of interdisciplinary subjects

  As the master planner of "online celebrity" food, Song Da always talks about his student team.

  Song Da came from a statistical background, and I know how to "play with" data best. After starting to work as a student, he added logistics-related contents to the campus satisfaction survey of the National People’s Congress: students’ taste preferences, the degree of solving canteen service problems, and "scoring your favorite canteen" all appeared on the questionnaire. Subsequently, the teachers and students of the School of Statistics will conduct big data processing to screen out the most useful information.

  Find out the taste and demand, and the rest is publicity and packaging. The promotion of "online celebrity cuisine" in the new media is "manipulated" by the students of the School of Journalism; Product design is free for students majoring in Chinese painting in the Art College.

  Before each new issue of "online celebrity" is released, Song Da and I will take the team to "meet the model" first, observe the shape and color of the cooked dishes, then understand their ingredients and preparation methods, then take photos and finally taste them. "Only in this way can we design a higher quality copy."

  The food design and dissemination of the National People’s Congress has benefited from the professional strength of this top comprehensive university. Luan Yimei, a professor at the School of Journalism, Renmin University of China, said that "online celebrity cuisine" can be a big fire precisely because of interdisciplinary cooperation among students. "We used to focus on the development of a single discipline and explain problems, but to really solve problems, we must cooperate across disciplines. ‘ Online celebrity cuisine ’ Starting from the needs of students, telling your own story well and grasping the law of communication will be welcomed. "

  Dishes are popular, and innovation is naturally more motivated. In the impression of Zhang Yiran, a sophomore in the School of Journalism, in the past year, the innovation of the school canteen has become greater, and new dishes will be introduced soon. This is also the change that Song Da expected to achieve. On Monday alone this week, more than 30 kinds of snacks were introduced in the North District canteen.

  Behind the new dishes, the logistics group "I am a chef" WeChat group studied and pondered at length. Last year, Song Da and I brought several canteen directors into a group. Usually, he would throw the good ideas he saw and thought into the group at any time to share, and sometimes they hit it off, forming offline products.

  For example, after the creativity of pumpkin bread reached an agreement, the central dining hall took the lead in setting an example, tying the bread into a strand with a string, which visually approached the appearance of pumpkin; The dining hall in the North District has worked hard on stuffing to turn pumpkin into a hidden "connotation"; The east dining hall also added sausage elements. "Everyone is competing for a competition. I didn’t expect the campus canteen to be so active." Song Da sighed.

  The youthful taste of productization

  After the Youth League became "hot", many graduates left a message under the article of WeChat WeChat official account, "What a pity! I graduated too early. "

  I found that the Youth League is not only a holiday food need for students in school, but also symbolizes a unique "symbol of the National People’s Congress" — — Students who have graduated expect to find campus memories through tasting, and teachers and students of the school also want to share this campus taste with relatives and friends. At the end of 2017, the Logistics Group officially planned to make the bulk youth league into a gift box set that can be sold.

  On March 26th, the Youth League gift box set was officially launched. The kraft paper bag used for packaging is printed with "memories of youth from the National People’s Congress canteen". The green ball stuffed with meat floss and egg yolk is called "this heart stumbles", and the green ball stuffed with pine nuts and bean paste is called "Acacia". A new green ball stuffed with fresh shepherd’s purse also has the same literary name — — "A thousand miles".

  Song Da I said, "The most fundamental duty of the school canteen is to meet the dining needs of students and ensure their food and clothing for three meals a day. On this basis, delicious food is also very important. We hope to bring students different experiences, enhance their campus happiness, and let the memory of taste buds rise to the cultural expression level of the National People’s Congress. "

  In addition to "going out" of products, they also attach importance to "bringing in" to supplement new energy for campus canteens. Last year, Song Da-i founded a series of activities called "Guest Chef RUC" with the logistics group, and invited elites from the catering industry in society and universities to come to the school for exchange.

  The activity was held in turn by five canteens of the National People’s Congress, and the directors of each canteen were secretly "competing". They invited the master of state banquet in the Great Hall of the People, chef Tan Jiacai of Beijing Hotel, members of the French Chef’s Association, and even a team of chefs who maintained the Guinness World Record.

  This activity has been successfully held for 12 times, and there is no funding for inviting chefs. I didn’t expect that the catering department of a well-known hotel would take the initiative to find it and ask to enter the school to cook for the students.

  Zhang Yiran has experienced several guest kitchens, and she still remembers the popularity of the event. "Hundreds of copies were sold out at once.". Now, she and her classmates are on the public platform of "Warm People’s Congress", waiting for the news released by the guest kitchen activities.

  Song Da, I feel gratified. He said that many new dishes had been introduced in the original canteen. Because of the asymmetric information, it was sometimes difficult for students to know the relevant information. After the trial period, these dishes were removed from the shelves with low sales. "The convenience brought by new media communication is mainly rapid. Students can quickly understand information, experience and give opinions quickly, and we can also make judgments quickly and adjust in time. "

A must-see for buying iPhone7. Here’s a strategy worth 3,600 yuan.

  Time flies. In a blink of an eye, most of the time has passed in 2016, and the long-awaited Apple conference will be held soon (September 7, US time, 1 am on September 8, Beijing time). At this juncture, are many small partners already holding back their hearts bought in buy buy, but what should they do with those they have just bought for less than a year? I believe that most people will choose to sell unless they have special friends (or small partners who intend to leave them for their families).

Who is the most cost-effective seller? How much is the iPhone in the eyes of friends?

  Who sells it and how to sell it has become a problem again. The author takes a 64GB rose gold version of the Bank of China (A1700) as an example. In terms of detailed conditions, we choose the machines that are within one month of the warranty period or expired, the bezel backboard is intact, the screen is normal without scratches, and everything is normal. How much are these worth among friends?

If so, will you still sell your 6s?


Recycling of e-commerce platform

  It is also very good to mention the development of e-commerce platform in recent years. Online shopping can enjoy preferential prices, and even the service system is becoming more and more perfect. For example, users can already trade in old ones online, buy new ones and sell old ones without leaving home. The author chose JD.COM Mall, Suning.cn and No.1 Store as the comparison platforms.

Jingdong Mall

  In JD.COM, we can see that the name of the trade-in service is "JD.COM Enterprise Recycling", which is divided into five or more enterprises recycling and five or less enterprises recycling and personal recycling. According to our previous conditions, the iPhone is valued at 2,885 yuan in JD.COM Mall (at present, the price of the new 64GB version of S in JD.COM Mall is 4,999 yuan), and consumers can choose to exchange the corresponding amount of JD.COM E-card or use Jingdong wallet to collect money.

  Judging from the situation of e-commerce platform, users can not only choose to buy upcoming or other brands after selling their old iPhone, but also withdraw cash if they are idle, which is also very convenient.


Manufacturer’s recycling

  In fact, many mobile phone manufacturers are launching trade-in services, such as Huawei, Meizu and LeTV, and the author chose these three brands for the price comparison of iPhone in the eyes of mobile phone manufacturers.

Huawei

Recycling page (picture quoted from Huawei Mall)

  In Huawei Vmall Mall, the recycling price of this iPhone 6s is 3,193 yuan, which is relatively high. However, it is more appropriate to choose recycling if you intend to abandon the iPhone and put it into Huawei’s arms, because the recycling money of Huawei Vmall Mall is only in the form of vouchers and can only be purchased in the mall.

MEIZU

Who is the most cost-effective seller? How much is the iPhone in the eyes of friends?

  Meizu’s trade-in is called "mCycle", and the recycling price of this iPhone is 2820 yuan, including the additional subsidy of Meizu in 120 yuan. Of course, just like Huawei, it also offers coupons, and only users can buy products from Meizu official website.

  Compared with the other two mobile phone manufacturers, LeTV’s recycling price is relatively high, which can reach 3,745 yuan under the same situation, in which the cash combination of 500 yuan LeTV Mall Universal Voucher+3,245 yuan is the highest among the recycling prices introduced by the author at present, and users can also sell the 500 yuan vouchers to needy friends at low prices, so that they can get more cash.

Who is the most cost-effective seller? How much is the iPhone in the eyes of friends?
Recycling price (picture quoted from LeTV)

  Judging from the prices of the three mobile phone manufacturers selected by the author for iPhone recycling, the price of LeTV is the most competitive, even if consumers intend to change to other brands after selling their old iPhones.


Professional recycling website

  The author selected three recycling websites: Love Recycling, Music Recycling and Quick Recycling. In terms of price, the maximum difference between the three companies is 858 yuan, which shows how important it is to choose the right platform.

Le recovery

Who is the most cost-effective seller? How much is the iPhone in the eyes of friends?
Recycling price (picture quoted from Le Recycling)

  In the evaluation, Le Recycle gave a quotation of 2800 yuan, which is the lowest compared with the ones mentioned by the author before.

Love recycling

Recycling price (picture quoted from Love Recycling)

  The price of the second love recycling store is 3,000 yuan (previously, JD.COM Mall and No.1 Store we introduced used love recycling to provide services), and the evaluation of love recycling on its own website is 100 yuan higher than that of the e-commerce platform.

Quick recovery

Who is the most cost-effective seller? How much is the iPhone in the eyes of friends?
Recycling price (picture quoted from quick recycling)

  In this comparison, the highest recycling price is quick recycling, and the evaluated price can reach 3658 yuan (excluding the combined price of LeTV coupons and cash). It can be said that if you choose the right platform, you can sell several hundred yuan more.


Write it at the end

  In addition to the upcoming release, September itself is a small peak of machine replacement. For many friends, how to keep the old iPhone in their hands at the maximum value has always been valued by the majority of users. Based on the author’s comparison today, if you believe in this quick recycling, you might as well sell your iPhone 6s at the highest evaluation price of 3658 yuan and wait for a new one. If you have doubts, you can also sell it to a more reliable LeTV. No matter what brand you plan to change next, the prices given by these two companies are still very cost-effective. If you still know more expensive recycling channels, let’s discuss and exchange them together.

Teach children math.

"A cabin is only 6 square meters. If you live in it, how will you decorate it?"


On December 25th, 2023, in the "Research and Practice Class of China Mathematicians Entering the Primary School Classroom" taught by Hua Yinglong, Vice President of Beijing No.2 Experimental Primary School, interesting questions deeply attracted the sixth graders.


The Mathematics Curriculum Standard for Compulsory Education (2022 Edition) points out: "The content design should reflect the application of mathematics in nature and society, show the great mathematicians in the history of mathematics development, especially the famous mathematicians in ancient and modern China, and the role of their mathematical achievements in the development of human civilization, and enhance students’ patriotic feelings and national pride."


It coincides with the 90th anniversary of the birth of Chen Jingrun, a famous mathematician in China. Hua Yinglong can’t help but think about the requirements of the curriculum standard: What kind of collision will happen when the world-famous China mathematician enters the primary school classroom? I want to chase the "brightest" star with my children!


Plant the seeds of curiosity


This class begins with the sharing of reading experience before class. Before class, the students previewed the reportage Goldbach conjecture in advance. In class, the students scrambled to share their feelings.


"Although some people discriminated against him, he didn’t waver in his love for mathematics. He was always calm, and his tolerant spirit was worth learning."


"I want to say to Chen Jingrun that you are really amazing. You were born in a family with no math environment, but you have made such achievements through hard work."


"What impressed me most was that Chen Jingrun studied hard in a 6-square-meter hut despite the difficult conditions."


…………


Students talked about being moved by Chen Jingrun’s spirit of studying and studying, and began to notice the mathematical element of "6 square meters" under the guidance of the teacher.


Hua Yinglong asked, "What kind of math topic do you think you can make up about the 6-square-meter hut?"


"Chen Jingrun’s room is 6 square meters, and their chimneys account for one-sixth of the room. How big is the living area?"


"The room is 6 square meters in total, and a chimney has cut the room into a corner, which is one-sixth of the room area. How big is this corner plus the total room area?"


…………


According to Hua Yinglong’s questions, the students expressed their opinions and collected five different proposition ideas. Hua Yinglong immediately gave his own examples. The students called "simplicity" and "logic", and an ordinary application problem set off a hearty "brainstorming" between teachers and students.


The reading method with "questioning" as the main guidance makes students experience the fun brought by mathematics reading, and guides students to think deeply and be eager to try after thinking.


After mastering more clues, students are more curious about the "6 square meter cabin". Hua Yinglong continued to ask: "What is a 6-square-meter cabin like?" He asked the students to draw a plan of the hut. With the help of students’ work sharing, Hua Yinglong has drawn out one enlightening question after another.


Through mathematics to restore the hut, children’s eyes look at the hut in a variety of ways: some are trapezoidal, some are square, some are marked with the position of the door and bed, and careful students mark the size of each layout …


"Teachers’ teaching design should read the world from a mathematical perspective, which is fascinating," Hua Yinglong said. "As a guide for students’ mathematics learning, we should plant a seed for them, hoping that one day, this seed will blossom a flower of’ everything counts’."


Bold trial and error in exploration


Around the "hut", Hua Yinglong took the students to solve the side length, and the "mathematical flavor" became stronger and stronger. At this time, a quick student confused the area and perimeter, and the students corrected his algorithm one after another. Hua Yinglong praised the student’s quick response and bold speech: "Children, in reading, not only reading, but also thinking. Every mistake is a reminder. We want to thank this classmate for reminding us." There was applause at the scene.


When calculating the side length of the hut, the students encountered a difficult problem-they had not touched the square root and could not continue to calculate.


"Children, we can’t make a square, can we still count?" Hua Yinglong asked. He didn’t impart knowledge beyond the outline, but left time for students to think. When a student tried repeatedly on the toilet paper and found the answer by reverse deduction, Hua Yinglong showed it to everyone with surprise and led them to summarize this valuable thinking process:


"Children, did this classmate try it right just once? No, he also found the answer by mistake, right? " Hua Yinglong once again guides students to correctly look at mistakes in learning. In such a class, students’ frustration tolerance is strong.


"Making mistakes is something everyone has to experience, including teachers." Hua Yinglong said, "We have to tell students that mistakes are often reminders, reminding us to calm down and think: Where is the problem? Why is it wrong? What new possibilities will there be? What new problems can you think about? "


"Where is the 6-square-meter hut and what is it really like?"


In order to give the child an accurate answer, Hua Yinglong shared his "journey to find the truth" after reading relevant books and materials, and went to the address of his former residence "No.88 Zhongguancun Street" in the materials to find out, but found that this was not the location of his mathematics institute. When I went to Fujian, I learned that there was a "Chen Jingrun Experimental Primary School" in the local area. I went there quickly, but I didn’t get the answer … Despite the twists and turns, with the help of Song Li, Chen Jingrun’s nephew, the real hut emerged a little bit: the room was square, and it became a "knife handle" shape after being occupied by the garbage passage. Because the space was narrow, people had to close the door before they could barely stand open …


Hua Yinglong’s exploration process of constantly trying to find a "real cabin" inadvertently set the best example for students.


Give students a bigger world.


"Students, suppose you enter Chen Jingrun’s cabin now, what do you want to say to him?"


As the class draws to a close, Hua Yinglong throws out the last question of this class. As early as in the open space next to the podium, he outlined the spatial structure of the hut with tape, suggesting that students take a walk in the "hut" and feel the living space of 6 square meters.


Some children bluntly said, "I love this mathematician very much, and I hope he will pay attention to his health and live in a big house." Some children felt "the sense of accomplishment gained by tireless knowledge" through repeated thinking, and some children called "Mr. Chen Jingrun is so great that in a difficult environment, he has confirmed the" Goldbach conjecture "that even the great mathematician Euler has not confirmed …


At this point, students’ feelings are not only the absorption after reading, but also the spiritual baptism after the classroom and teachers jointly verify and explore.


The students read the ten characters written by Hua Yinglong on the blackboard in unison-"A humble room grows into a superstar, and hardships make a great man". At that moment, the little boy seemed to have crossed time and space, ignorant and firmly paying tribute to the mathematician.


What can mathematics leave for students?


"A good math reading class is to give students reading energy and spiritual nourishment." Hua Yinglong replied in class, "I always think that education is humanized, which is the highest realm pursued by education." I am a primary school math teacher, but I don’t teach math. I use math to teach children. "

Don’t panic when your phone is out of power. Jing’an has these charging-friendly places.

The emergence and popularity of shared power banks has alleviated people’s "low power crisis" to a certain extent, but it has also been widely controversial for its "higher and higher prices and slow charging".

In recent months, topics such as "Is it expensive to start with 4 yuan per hour for a shared power bank?" "The shared power bank is only 30% charged when the electricity is used up" have frequently hit the hot search, causing many netizens to resonate and complain.

Not only is the price becoming more and more "assassin", but when the mobile phone battery is only 1% or 2%, you can scan the shared power bank. You may also encounter the dilemma of automatically shutting down the phone before the power bank pops up halfway through the scan.

As the Mid-Autumn Festival and National Day holidays approach, I believe that many people with travel plans will write in the memo "carry a data cable with you when you go out", and charge it for a while when you encounter a place that can be charged, in case of emergencies. So, what are the charging-friendly places in Jing’an? Jing Bao has collected the following for you –

In recent months, have you noticed these red and black color schemes and stylish new public telephone booths on the streets of Shanghai?

Digital phone booth on Yuyuan Road

This rejuvenated digital phone kiosk carries the functions of one-click ride-hailing, sign language video, mobile phone charging, free calls, and other inclusive and convenient services.

Among them, the charging function supports wired and wireless, even if you don’t carry a data cable with you when you go out, you can charge it by the way after sitting in the public phone booth for a while.

Jingbao tested the wireless charging function for everyone at a digital phone booth on Yuyuan Road, which is very convenient.

Want to know where all the digital phone booths with this function are? Just search for "HELLO Friends Pavilion" in the map APP of your mobile phone. The map shows that there are 7 points within one kilometer of Jingbao’s location.

At present, digital public telephone kiosks have covered 13 administrative districts in the city, and it is expected that 1,000 will be built by 2025, gradually expanding the coverage and increasing the coverage density.

Have you ever charged while riding the subway? If you take the subway line 14 at Jing’an Temple, you will find that there are 4 USB charging ports at the head and tail connections of the carriage. After putting down the folding plate, you can use the built-in charging cable to charge. You can also charge it during the journey, which is very time-saving.

The logo shows that the output of this interface is 5V~ 1A, and the output power is 5W. After Jingbao sat for 3 stations from Jing’an Temple, the mobile phone was plugged in for about 8 minutes when arriving at Yuyuan Station, and the power increased by about 6%.

According to Shanghai Metro staff, there are usually charging ports in the cars of newly opened lines, while "old lines" have some train cars. For example, each car of Line 18 trains is equipped with wireless and wired charging devices, and some trains of Line 1 and 2 are also equipped with USB charging ports. In addition to the cars, the service center in the subway can also provide emergency charging services.

The staff at the in-app service center of Jing’an Temple Metro introduced that passengers can charge their mobile phones at the service center when they travel with low battery, and they do not need to bring their own charging cable. However, different service centers have different requirements on whether they can bring their own cable. Some said that for safety reasons, they must use the charging cable of the service center, and some said that they can also use it if they bring their own charging cable.

Reminder:If you are charging while taking the subway, please don’t forget to unplug the cable when getting off, and don’t forget to take your mobile phone with you.

At present, many street community activity centers have activity rooms, study rooms, and reading rooms, all of which provide sockets for citizens and tourists to charge.

Taking the Party and Mass Service Center on Jing’an Temple Street as an example, the library on the third floor is equipped with a sufficient number of sockets. However, it should be noted that this free charging place does not have a USB port, and citizens and tourists need to bring a charging plug to charge.

Reminder:When charging in the activity center of the street community, all public orders of the venue must be observed.

In addition to the above places, there are also many free charging sockets in some commercial cafes, but generally speaking, "charging stations" are very popular, and it is very likely that they will be "full".

Jing Bao visited some chain coffee shops in the Jing’an Temple business district. Generally, chain coffee shops with many seats and large areas will provide free charging sockets, such as Jing’an Kerry Center and Starbucks of Jiuguang General Merchandise, and M Stand of Jiuguang General Merchandise, etc., but many of them have been "first come, first served".

For citizens and tourists, it is a good choice to sit down and order a cup of coffee while charging, but if you encounter a large traffic in the store and there are no free charging sockets, you need to try your luck.

CS2 may open the global public beta IGXE, NetEase BUFF, Tieba players continue to debate

  Recently, V Agency has released the update information of the cs2 beta version again. The map and a number of game adjustments have made players feel that the official version is not far away, and Tieba players are also squatting for various update clues. Many jewelry players have noticed price fluctuations of some weather vane jewelry on platforms such as IGXE and NetEase BUFF. Is the epic update coming at any time after a decade?

  (CS2 gun skin display)

  CS2 closed beta opens nine maps, with the latest adjustments to multiple games

  Currently in Casual and Deathmatch mode, CS2 has been able to play all maps from the previous limited test period, including: Italian Town Italy, Sand City Dust II, Nuclear Crisis Nuke, Desert City Mirage, Death Amusement Park Overpass, Office Office, Vertigo, Anubis, and Ancient Ruins. Currently Inferno is the last map in the active map that has not been added to CS2.

  (CS2 closed test map update)

  In addition to the map, there are also many adjustments in the game: the responsive smoke bomb is significantly narrower than the previous range, higher in height, and can also react to factors such as in-game lighting, bullet shooting, and explosions. Another small detail is the addition of character shadows, which can assist in judging the movement of characters in the game, and C4 will no longer sink into the water. In addition, there are already live streaming hosts who have started to play wine bottle plate shooting, fruit cutting, etc., and the interaction between the map environment and characters may also become a new pleasure.

  Previously, the CS: GO ranking matching system has been widely criticized by players. Plugins and high-ranking player trumpets are full of them, which has a significant impact on the fun of ordinary players. Regarding this, V Club revealed that it will follow the plan to redesign the matching system. At the same time, it may switch to MR12 default settings instead of MR15 in competitive matching (the first round is 13 rounds instead of 16 rounds). Through continuous optimization and updates, I believe that the game environment of CS2 will continue to improve.

  Players crouch to update clues IGXE, NetEase BUFF platform undercurrent

  In recent weeks, Valve has been increasing the update frequency of cs2, and players’ hearts have been affected every three days. Recently, in the csgo game Tieba, there are careful players who said that there is one less news announcement in the game. According to the previous practice, the game will usher in a big update. Although there is no official basis for this clue, it can be seen that players are looking forward to the arrival of cs2.

  (Price trend of butterfly knife raw leather on IGXE platform)

  At the same time, jewelry players and merchants on the IGXE and NetEase BUFF platforms are also on the line. The price of butterfly knife leather, known as the weather vane of the jewelry trading market, has risen on the IGXE platform since late July, and has returned to more than 14,000 yuan, and is still rising. In addition, the prices of popular gun skin series such as marble and Kepler that have worked well in the update test are also taking off silently. The overall situation is like the news released by the V official announcement of cs2 in March this year. The official platform, players, and three-party trading platforms are all waiting for an update storm that has been brewing for ten years, and their respective undercurrents are surging.

  (IGXE platform claw knife gradually changes the price trend of marble)

  It can be said that the update of cs2 may come at any time this summer. For jewelry merchants, it may be the most important market trend this year. For ordinary players, they are actually more concerned about the update of the game image quality experience and the improvement of the game matching environment. Having fun is the meaning of the game. If you want to experience the updated skin effect without wading too deeply, it may be a more cost-effective choice to have a skin rental experience on a reliable platform like IGXE. After all, the skin effect in the final game still has to wait for the official version to be launched.

The map of the Lantern Festival in 2023 is released. Let’s go and see where the moon lights and the snow lights.

  China Weather Network News "Colorful flowers and thousands of trees, colorful night sky", the annual Lantern Festival is coming, the second day of this year’s beginning of spring solar term is the Lantern Festival, and the two festivals are closely linked, which can be described as double happiness. Going out to enjoy lanterns on Lantern Festival is a traditional folk activity in China. What’s the weather like around the Lantern Festival this year? China Weather Network specially launched the Lantern Festival Lantern Festival index map, to see where there will be lanterns this year, and where to enjoy the snow and light the lanterns.

  Most of the weather in the north is sunny, and the moon is accompanied by lights. In the south, it rains and lights.

  Lantern Festival is also called Lantern Festival in ancient times. On this day, every household hangs lanterns or goes out to enjoy them. The city is decorated with lanterns and the night is like day, which sets off the lively and festive atmosphere to the extreme.

  According to Zhang Juan, a meteorologist of China Weather Network, this year’s Lantern Festival (February 5), the weather in most parts of northern China is beautiful, mostly sunny or cloudy, such as Harbin, Beijing, Tianjin, Shijiazhuang, Taiyuan, Xi’ an, etc. It is sunny on this day, so it is suitable to go out and enjoy the lanterns and feel the beauty of the bright moon with lanterns. Shenyang, Changchun, Jinan, Zhengzhou and other places have more clouds in the sky, and the "clouds with lights" are more poetic.

  "On August 15th, Yun Zheyue, it snows and lights up on the 15th day of the first month" is a popular proverb in China. Snowfall at midnight snack this year is relatively small, and only snowflakes may appear in northern Xinjiang and southeastern Tibet, so the romantic friends who can feel the snow with lanterns this year can be said to be very lucky.

  In the south, this year’s Lantern Festival is another scene. It is estimated that except Yunnan and Hainan, which are favored by the sunshine all the year round, most southern areas such as Guizhou, Hunan, Hubei, Anhui, Zhejiang, Jiangxi, Fujian, Guangdong and Guangxi will be rainy, with some areas in Guangxi, Guangdong and Jiangxi having strong rainfall and local or current heavy rain. Friends in the above areas need to carry rain gear with them when going out to enjoy the lanterns, and be careful of slippery roads. If the rain is too strong, it is also a good choice to stay at home and enjoy the lanterns with relatives.

  The North-South Lantern Festival is full of excitement, and the equipment for enjoying lanterns is different.

  Lantern Festival Lantern Festival has been preserved as a traditional folk activity in China, and the annual Lantern Festival in all parts of the country has its own characteristics, such as Beijing Longqingxia Ice Lantern Festival, Shanghai Yuyuan Lantern Festival, Sichuan Zigong International Dinosaur Lantern Festival, Guangzhou Cultural Park Lantern Festival, etc. It has a long history and many tourists come here every year. In some cities that used to be ancient capitals, such as Xi ‘an and Nanjing, in recent years, the Lantern Festival has been combined with the culture of ancient capitals, so that tourists who are in the sea of colorful lights and Hanfu can "cross" in a second and dream back to Chang ‘an and Jinling.

  According to the forecast, there may be rain on the Lantern Festival in Shanghai, Zhejiang, Jiangsu and Guangdong this year, and the feeling of wet and cold is also obvious. The public who plan to visit these lantern festivals should pay attention to carrying rain gear and adding clothes to keep warm. Although the weather in Beijing, Shandong, Shaanxi and other places is mainly sunny or cloudy, the temperature at night is low and the chill is online. When you go out to enjoy the lights, you can choose a thick down jacket and wear a scarf and hat to keep warm. People are crowded during the Lantern Festival, and cold viruses are easy to cross-infect. Everyone should wear masks and do a good job in health protection.

  The custom of Lantern Festival celebrates reunion and family fun together.

  In fact, besides enjoying lanterns, there are many other traditional customs and folk activities in China, such as eating Lantern Festival, solve riddles on the lanterns Lantern Festival and Youlong Lantern Festival, and each custom also represents a different beautiful meaning.

  1. Eat Yuanxiao/Tangyuan

  The north "rolls" Yuanxiao, and the south "wraps" glutinous rice balls. Although the food is different, the beautiful implication is the same: good luck and happy reunion. For China people, it is a very happy thing to be able to sit around and eat the round Lantern Festival and pray for a better life together during the Lantern Festival. For some wanderers in a foreign land and overseas, eating a bowl of Yuanxiao or glutinous rice balls on the Lantern Festival also expresses their yearning for their hometown.

  2. solve riddles on the lanterns

  Solve riddles on the lanterns, also known as playing riddles, is a popular Lantern Festival activity since ancient times. On the fifteenth day of the first lunar month, people hang lanterns, so some people write riddles on paper and stick them on colorful lanterns for passers-by to guess. Because riddles can enlighten wisdom and cater to the festive atmosphere, so many people responded, and later solve riddles on the lanterns gradually became an indispensable traditional program of the Lantern Festival.

  3. Youlong lamp

  In Sichuan, Fujian, Zhejiang and other places in China, Youlong lanterns are also an important way to celebrate the Lantern Festival. In many places, there is a custom that "the fire dragon goes around the countryside and the people make Lantern Festival". Everyone expresses the significance of exorcising evil spirits, eliminating plague and praying for a bumper harvest by dancing dragon lanterns. Large dragon lanterns with bright colors walk through the streets with the sound of gongs and drums, which is very festive and bright.

  4. Walking on stilts

  The homonym of "stilts" is "look up". Performing and celebrating on stilts on the Lantern Festival means that in the new year, people should be far-sighted and make plans for the whole year in advance. At the same time, when walking on stilts, because you step on a high wooden pole, your body will also rise, so walking on stilts also means rising step by step.

  According to the Beijing Planetarium, there will be the smallest full moon this year in the early morning of the 16th day of the first lunar month, which is somewhat special. It is not only the first full moon in the year of Guimao Rabbit, but also the smallest full moon in 2023. Friends who are interested in "looking forward" to the moon can watch and shoot about two hours after the Lantern Festival.

  The Lantern Festival is coming, I wish you all the best to enjoy the lights and the moon, and the full moon will be a reunion. (Text/Ma Heiyang Data Support/Zhang Juan Design/Ren Chengying)
