"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. "

China Education News, January 5, 2024, 9th edition.　

The new energy market has entered the second half of competition, and many traditional independent brands have made great moves frequently, among which Changan has brought the brand-new brand of Deep Blue Automobile, which operates independently. Just a month ago, Deep Blue S7 was officially launched as the brand’s first SUV model. Although this car has not been on the market for a long time, it has also attracted widespread attention from netizens, and its popularity and voice are very high at one time. I am very curious about such a car that is born out of traditional manufacturers, relies on its quality endorsement and channel advantages, and at the same time has a young scientific and technological image comparable to the new forces. Therefore, we came to the experience center of Deep Blue Automobile in Beijing to visit it on the spot, from the sales channels, market performance to the product itself to see if this newly-launched popular newcomer has the strength to be firmly selected by more consumers.

The new and old channels are parallel, and the service gap is large.

Open the applet of Deep Blue Auto and you can find that it has 16 experience stores in Beijing. Among them, there are 8 direct-operated stores of Deep Blue, that is, the independent sales channel opened by Deep Blue Automobile as a new brand, while the rest of the experience stores rely on Changan Automobile’s original 4S store dealer channel for sales. In two working days, we visited two dealer stores and a direct store respectively, and what we saw and felt was very different.

We first came to a dealer’s shop in the North Fifth Ring Road, Chaoyang District, Beijing. The signboard of this shop was written with the words Chang ‘an Dark Blue, but after entering the store, we almost saw all the models of Chang ‘an Automobile, but there was no dark blue model. After asking the salesperson, I learned that a pure electric version of Deep Blue S7 had just arrived in the store and was parked in the parking lot outside.

At the parking lot, the salesperson first fumbled for a while with the key of the dark blue S7, but he couldn’t unlock the vehicle by any means. During this period, a passerby asked if the dark blue SL03 next to him could get a green card, and the salesperson replied: I think so.

After that, we successfully got on the bus and had an experience. After the experience, we went back to the store to get to know more, but the salesperson didn’t come back after serving two glasses of water. After waiting for about two songs, we decided to leave on our own. It must be noted that the time for us to look at the car was at noon on weekdays. Except for us, there was only one group of customers in the store at that time, so there was no situation that we were too busy.

After coming out of this store, we were really more curious about Deep Blue Auto, so we went to a direct-selling store of Deep Blue Auto near the East Fifth Ring Road in Chaoyang District, Beijing, where we felt a completely different experience.

First of all, the sales staff of this direct store explain the models more professionally and clearly, which can really greatly enhance the customers’ willingness to choose. At the same time, what impressed me the most was the test drive, because the road conditions around this store are complicated, with high-speed and potholes. The salesperson asked what kind of road experience to choose, and of course, you can drive them all. To tell the truth, this has really restored my good impression of Deep Blue Automobile to several points. The core pursuit of the store is to sell cars, but the core and more basic thing is to let interested customers experience the products as comprehensively as possible.

Deep Blue Automobile relies on the big tree of Changan Automobile, and the most beneficial thing is the mature sales channel system. If it is a start-up brand, it must build a sales channel from scratch, and the success of the channel greatly affects the conversion rate of sales leads and the delivery ability of the brand, and then affects its development. Deep blue automobile, from its birth, has the intensive sales channels of Changan Automobile in large and small cities all over the country, which can make it easier for more interested customers to see and mention cars, which will greatly benefit the development of the brand.

Even Deep Blue Auto itself said that its marketing model combines the advantages of the existing 4S shop model and direct sales model in the automobile industry to ensure that every new car of Deep Blue Auto has a perfect service system. However, in reality, there is no such thing as both.

The traditional dealer channel is mature and spread all over the market, but the 4S store model basically determines this channel, and the average level of service is not comparable to that of direct stores. On the other hand, direct stores are good everywhere, but it takes money and time.

As of July this year, Deep Blue Auto has laid out 746 order centers, 390 mobile exhibition halls, 427 delivery centers and 528 maintenance centers nationwide. Among them, we don’t know the proportion of direct mode, but it must be less popular than 4S shop mode. Before the launch of Deep Blue S7, there was only one model of Deep Blue, SL03. It is really not necessary to build a new system for such a small volume. However, with the arrival of Deep Blue S7, Deep Blue Auto has gradually embarked on the track of stable development, and at the same time, gradually increasing the investment in direct-operated stores is the full force that the new brand should have.

Top-of-the-line models are the best sellers, and you have to wait at least one month to book a car.

During the visit, we paid special attention to the sales of Deep Blue S7. According to the sales staff of direct-operated stores, the most popular models of Deep Blue S7 at present are the extended-range top version, the 200Max version with a price of 169,900, and the pure electric top version, the 620Max version with a price of 202,900.

As can be seen from the configuration table of Deep Blue S7, except for the most basic 121Pro extended range model, the other models, whether extended range or pure electric version, only have differences in power form, data and cruising range, and the other configurations are almost the same, so the choice of configuration depends on whether you are willing to spend more money to choose a higher cruising range. In the extended-range version, the price of the top-matching sub-top-matching is 10 thousand yuan, which is 79km more pure battery life; In the pure electric version, the top-to-bottom ratio is 13,000 yuan more expensive, and the pure electric battery life is 100km more.

In addition, the delivery cycle of Deep Blue S7 is at least 4-6 weeks, and it may be 5-8 weeks longer. The difference in time depends on whether it is optional or not. In fact, the most important optional package of Deep Blue S7 is the extrasensory intelligence package which includes the zero-gravity massage seat of the main driver and the 12.3-inch entertainment screen of the auxiliary driver. The optional price is 12,000 yuan. From my personal experience, I think the extrasensory intelligence package is worth choosing, which can also be regarded as a highlight of Deep Blue S7. Press the TV mode button, the passenger seat will lie back and the passenger screen will turn down, which is definitely an artifact for long-distance travel.

Younger style, configuration to avoid entanglement

In recent years, the models of Changan Automobile generally give people a strong sense of youth. As a new brand and a new energy vehicle, Deep Blue S7 shows a free and easy youthful temperament.

In terms of appearance, Deep Blue S7 is not a new force, but it is no less dynamic than the new force. The family appearance of the dark blue car is still dynamic and sharp on this SUV, and the split headlights are full of movement with the vents on both sides. Compared with the conventional SUV, the side of the dark blue S7 is lower, which makes its drag coefficient only 0.258Cd. In terms of body size, the length, width and height of the new car are 4750/1930/1625mm respectively, and the wheelbase is 2900mm.

When entering the car, the Deep Blue S7 uses the central control screen and the "sun visor" co-driver screen, which is unique among the traditional self-owned brands and has a memorable innovation in form.

In addition to aesthetic feeling, the configuration performance of deep blue S7 is also very bold. The entry-level version of the model is already rich in configuration, and the common comfort and safety configurations are basically not absent. In addition to the entry-level model, other models of Deep Blue S7 are equipped with L2 intelligent driving assistance, 3 millimeter-wave radars, electric trunk, adaptive far and near light, 15.6-inch sunflower screen, heating and ventilation of driver’s seat, electric seat memory and other configurations as standard, which saves the user’s entanglement in configuration selection.

As a big five-seat positioning model, the deep blue S7 space is also its advantage, and the seat material is soft and has good wrapping, which is very important for users who pursue practicality and space utilization. If you pursue a more comfortable experience, you can also choose a zero-gravity seat. The main driver’s seat supports 16-way electric adjustment, and heating, ventilation and massage are all equipped.

Deep blue S7 also provides two power forms, pure electric and extended range, both of which adopt single motor rear layout, and the cruising range of pure electric CLTC is 520km and 620km respectively. The range extender of the extended-range version is a 1.5L naturally aspirated engine, with the maximum power of 70kW, the peak power of the driving motor of 175kW, the pure electric battery life of 121km and 200km respectively, the fuel consumption of feed of 4.95L/100km, and the maximum comprehensive cruising range of 1120km. In the whole automobile market, endurance performance also belongs to the first echelon.

summary

From channel construction to product strength, it is not difficult to find that Deep Blue Automobile has always had mature manufacturers as the foundation, which also makes it have a more stable and long-term development. At the same time, the dark blue S7 model itself is a distinct personality in its class, and its core qualities such as price and configuration are also sincere, so it will be a good choice as an urban car for young people or young families.

The configuration performance of is a point that consumers pay more attention to. Let’s take you to appreciate its style.

Let’s take a look at the appearance of Buick GL8 first. The front face of Buick GL8 looks clean and refreshing as a whole, and it is very recognizable with multi-frame grille. Coupled with the angular headlights, the overall look has a certain sense of hierarchy. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing and so on. Coming to the side of the car, the body size of the car is 5219MM*1878MM*1807MM, and the car adopts unique lines, which gives people a very elegant feeling. With large-sized thick-walled tires, the shape is eye-catching. In the rear part, the tail line of Buick GL8 is clean and fresh, the taillight style is relatively young and fashionable, and the exhaust pipe uses a hidden design, which is relatively simple in general.

Coming into the car, the interior of Buick GL8 looks very domineering and stylish, and the visual effect is good. The steering wheel of the car is very in line with the interior style, made of genuine leather, and has a full and delicate grip. From the central control point of view, the design of the center console is reasonable, which makes the interior design quite layered and conforms to the mainstream aesthetics. The interior feels good. Let’s take a look at the dashboard and seats. The car is equipped with a sharp dashboard, which looks very simple and fashionable. The car uses leather seats, equipped with functions such as electric adjustment of auxiliary seats, electric adjustment of seats, and seat proportion tilting, which improves the riding experience of drivers and passengers.

Buick GL8 is equipped with car networking, remote control key, Bluetooth key, rear wiper, interior atmosphere light, engine start and stop, etc., which is worthy of praise.

What’s your main impression of this car after reading the whole article? This class of cars is usually the first choice for most people. First of all, the price is not expensive, and secondly, all the configurations are quite complete, which is still very worth starting with.

In 2025, Huawei HarmonyOS Zhixing will launch a series of new models, including Wenjie M8, Xiangjie S9 extended version (including extended version and travel version), Zunjie S800 and Zunjie’s second model.

The M8 is expected to be unveiled in the first half of 2025, and its design concept will compete with the ideal L9, and the estimated price will also overlap. Judging from the spy photos and patent drawings, the M8 will adopt a brand-new ring-shaped headlight design, and the rear will adopt a brand-new style of penetrating taillights. The overall shape pays attention to space practicality. In addition, the M8 will be equipped with a laser radar, and there are three penetrating triple screens in the car. Although the screen size is smaller than that of the M9, it is full of science and technology. The new car will also be equipped with a head-up display and Huawei’s exclusive audio system to provide drivers and passengers with a more comfortable and intelligent driving experience.

Enjoy S9 spy photos.

The spy photos of the extended-range version of Enjoy World S9 have been exposed. The design of the new car is consistent with that of the pure electric version, but the specific details of the power system have not been announced. In addition to the standard models, Enjoying S9 will also launch extended and travel models to meet the needs of different consumers. The launch of these models will further enrich the product line of Huawei HarmonyOS Zhixing and provide consumers with more choices.

Zunjie S800 is another masterpiece of Huawei HarmonyOS Zhixing. Yu Chengdong, managing director of Huawei, once said that Zunjie S800 will exceed people’s imagination and be more luxurious, higher-end and smarter than Rolls-Royce Phantom. In addition to Huawei’s latest equipment, Zunjie S800 is expected to provide a more luxurious ride in the back, with two independent seats. The new car is scheduled to be launched before the spring of 2025, which will become a highlight in the market.

In addition to the Zunjie S800, the second model of Zunjie is also planned to be launched at the end of 2025. Although the specific information about this model has not yet been announced, it is foreseeable that it will still be equipped with Huawei’s latest smart driving technology and car-making concept.

　　Among all the stars in the Chinese mainland, only Angelababy became the only one who became famous in English.

　　

　　Many people are familiar with the name Angelababy, but they are unfamiliar with the name Yang Ying.

　　

　　So why is Yang Ying called Angelababy? How did this name become popular?

　　Angelababy was born in Shanghai on February 28, 1989. She is of Chinese-German descent and her Chinese name is Yang Ying. She is a true Chinese.

　　

　　Angela (Angela) is a woman’s name. Zhang Shaohan’s English name is Angela Zhang, and Li Xiang’s daughter’s English name is Angela, which is also the name of a Japanese animation singer group. Baby means baby, in addition to calling children, you can also call your beloved. Angel is the English of "angel", and AngelaBaby is connected together, which means "angel baby".

　　

　　Angelababy’s English name was Angela when she was a child, but her classmates thought the three sounds of the name were too difficult to pronounce, and she had Baby Fat, so they were all called Baby. When she hosted the Disney show, she used Angela back, and later didn’t want everyone to confuse her name, so they combined to become the current angelababy.

　　

　　Afterwards, she made her debut as a model and turned her acting career to the big screen in 2007. She grew up step by step, becoming increasingly known as angelababy.

　　In recent years, her popularity has skyrocketed and her career has blossomed: she has been in the top 100 of the Forbes China Celebrity List for three consecutive years, and she has attended international events such as Paris Fashion Week, Milan Fashion Week, and the Venice International Film Festival.

　　

　　After Angelababy became famous, the Chinese name Yang Ying was rarely used. The media and fans only remembered the name Angelababy, and for convenience, everyone called her baby.

　　

　　Angelababy smiled and said, "But I still like my family to call me by my real name, Yang Ying, in Shanghai dialect. It feels the most cordial!"

　　

　　Now she and Huang Xiaoming are happily together, and on January 17, 2017, they ushered in a new life together. From then on, 1 + 1 = 3.
