EZ-6 suspected price exposure, 221,800 yuan this price is really bad!

Recently, a Changan Mazda EZ-6 car purchase invoice caused an uproar among netizens. The invoice clearly shows that the price of the EZ-6 pure electric BEV model is 221,800 yuan. This news has caused many industry insiders and consumers to discuss. Many people believe that the EZ-6, as Changan Mazda’s first new energy product and the only model in the joint venture B-class sedan market to provide range-extending power, is mostly true. Moreover, Changan Mazda is really not good this time.

First of all, start from the authenticity of the invoice. This car purchase invoice was issued on August 16, more than a month earlier than the pre-sale time. Generally speaking, a new car is launched, and the car company has a complete set of time to advance the process. Especially for a joint venture car company like Changan Mazda, it is very possible to negotiate the price 2 months in advance. In addition, although sensitive information such as invoice codes are coded, from the information of the invoicing party and the invoice seal of Changan Mazda Automobile Co., Ltd., this invoice does not seem to be fake, and it is likely to be internal information. To sum up, the invoice itself is very reliable, and the displayed EZ-6 price is also likely to be real data.

In fact, since the EZ-6 made its debut at the 2024 Beijing Auto Show, the car has quickly become one of the hottest discussed models in the joint venture new energy field. The reason why it has attracted a lot of attention is not only its design that stands at the forefront of the trend, but also because the EZ-6 is the only model in the current joint venture B-class sedan market that offers extended range power options, which to some extent makes up for the gap in the field of extended range of joint venture new energy models.

In-depth understanding of the product characteristics of the EZ-6, in terms of body size, the length, width and height of this model are 4921/1890/1485mm, and the wheelbase is 2895mm. The EZ-6 features frameless doors and hatchback design, which undoubtedly make its shape full of modern and futuristic. However, the design of the through taillights and the four round barrel lights on the sides makes people think of classic Mazda design elements.

In terms of power configuration, the EZ-6 provides consumers with both pure electric and extended range options, and adopts a rear-drive layout. According to the information currently exposed, the power parameters of the pure electric version are all 190kW, while the extended range version models use the same 1.5-liter range extender, and the power parameters are exactly the same. In terms of endurance, according to the different battery pack capacity, the endurance range of the pure electric model is 480 kilometers and 600 kilometers respectively, while the extended range model can achieve a long battery life of more than 1,300 kilometers under the condition of one charge and one tank of fuel.

In terms of smart configuration, the EZ-6 is full of sincerity. Equipped with the third-generation 8155 chip of Qualcomm Snapdragon, it is equipped with a 14.6-inch floating center control screen, plus a full LCD instrument panel and an AR-HUD head-up display, which makes smart technology feel overwhelming. In addition, the vehicle is also equipped with 360-degree panoramic images, 180-degree panoramic chassis, adaptive cruise control, lane keeping assistance, automatic parking and other functions. Luxury is reflected in its equipped Sony audio and 64-color ambient lights, as well as zero-gravity seats, which are very rare in the same class of models.

Judging from the configuration of the product and the price of other models, the pricing of the EZ-6 seems very reasonable. From the known information, the EZ-6 has far exceeded most joint venture models in terms of configuration. Moreover, as a joint venture pure electric mid-range car, the price of 221,800 yuan is quite competitive compared with the price of about 300,000 yuan for Tesla Model 3 and BMW i3, and the starting price of 227,700 yuan for Volkswagen ID7. This undoubtedly gives the EZ-6 a strong price advantage in the market.

According to Mazda’s previous pricing strategy, the price of the EZ-6 is expected to fall between 18-240,000 yuan. If there are some awesome policy support during the pre-sale period, it will surely further enhance the market competitiveness of this car. According to the latest news, the EZ-6 will start pre-sale on September 28 and is scheduled to be officially launched at the end of October, which has brought a lot of pressure to other joint venture new energy models. Overall, Changan Mazda’s strategic layout this time is obviously very wise, and the EZ-6 is very likely to become a new spoiler in the market.

Behind every successful model is a comprehensive market survey and strict strategic deployment. Whether this expectant Changan Mazda EZ-6 can stand out in the fierce market competition still needs further testing by consumers and the market. Welcome to share your views and expectations of this car in the comment area. We are waiting for the final answer to be revealed together!

Equipped with the GAC Xingling architecture, the smarter and more IKEA Trumpchi new energy E8 is here!

On November 17th at the Guangzhou Auto Show, GAC Trumpchi launched a new technology brand – Trumpchi Intelligent Electronics Technology i-GTEC, which integrates China’s strongest three electric, high-end electronic and electrical architecture, high-performance intelligent driving, emotional intelligent cockpit and other leapfrog performance, which is more advanced than "super". At the same time, the Trumpchi new energy E8, which has recently broken through the "circle", was officially launched, and a total of 2 models were launched, of which the 150km PRO version 209,800 yuan and the 150km MAX version 229,800 yuan. It is reported that without announcing the detailed configuration and price, the blind order of the E8 broke through 20,000 units.

If this year’s "fairy fight" MPV market is compared to a competition examination venue, Trumpchi New Energy E8 is undoubtedly one of the enviable "top students" on the field. As a "new player" entering the MPV market, E8 can be said to "stir up a thousand waves with one stone". While many MPVs are still struggling to think about the "standard of excellent family cars", Trumpchi New Energy E8, which is full of "smart" and "practical" buffs, has obviously handed in a satisfactory answer in advance.

The strongest brain, enjoy smart travel

Modern families’ demand for cars has extended from meeting basic travel and safety to pursuing quality and convenience, and the demand for the intelligence level of family cars is naturally increasing. However, many MPV models on the market are only equipped with the most basic intelligent functions, and the integration of intelligent systems is low. There are also certain problems in reliability and stability.

The Trumpchi New Energy E8 is equipped with the latest GAC Xingling electronic and electrical architecture, which is like the "strongest brain" and can achieve "one call and one response". When MPVs of the same level are still exploring how to improve the reaction speed of function keys and can only open applications "one-to-one", the E8 has achieved "far ahead" on the intelligent track. The Xingling architecture has been fully upgraded, the overall computing power has been increased by 50 times, and the data transmission rate has been increased by 10 times, which can help the E8 run a larger amount of data at a higher speed in a short period of time, giving users a smoother and silkier driving experience. The vehicle’s multi-domain linkage allows users to experience the sense of control of "military advisor" when driving the E8, and can mobilize multiple intelligent applications in the whole vehicle at the same time with just "a single order", with full marks for execution. At the same time, the E8 can also support global OTA updates of in-vehicle software throughout the life cycle, achieving second-speed iteration, greatly improving OTA efficiency and stability.

With the "strongest brain" of the Starspirit architecture, E8 is like an all-round housekeeper who can solve problems for the family, meeting the needs of the whole family at the same time, leaving more time for us to chat and share joy with our families during the journey.

Intelligent interaction, "words" express what you feel and think

As people’s lifestyles change, the demand for car driving experience is also increasing. In this era where smartphones are frequently criticized for "blocking family ties", the balance of technology and emotion is undoubtedly an important test for a family car.

The E8 is equipped with the ADiGO 5.0 system that has been fully optimized on the basis of the original intelligent interaction. With the support of the Qualcomm Snapdragon 8155 chip, with the 14.6-inch high definition LCD central control screen and the 8.88-inch new instrument, the content is clearer and more intuitive, and the scene service is more appropriate, making the user experience more arbitrary and fast. The new VPA "Xiaoqi" adds a touch of "home" warmth to human-computer communication through natural anthropomorphic voice and natural logic dialogue. Not only that, but the millisecond-level wake-up speed is always available, always responding to the needs of every family. When a family sits on the E8 to start their journey, whether it is a child who wants to sing a nursery rhyme, a lover who wants to watch a movie, or an elder who wants to listen to a "talk about the ancient times", as long as they express their thoughts, Xiaoqi can always come to the side and serve as the most "home" company on the journey.

An excellent family car, of course, also needs to be responsible for the safety of the whole family. Taking into account the fatigue that may occur during long-distance driving, and the different driving levels of each family member, the E8 is equipped with a powerful "assistant master" ADiGO PILOT super-sensory intelligent driving system. Under 10 comprehensive L2-level intelligent driving aids, the urban congestion is not tired, the automatic braking is safe, and the 540 ° high definition panoramic image is transparent and visible under the car, so that the driver can clearly perceive the wheel position and the road conditions under the car, whether it is walking through the streets or crossing mountains, it can be easily driven.

2311230937402121736731

A "three-headed and six-armed" housekeeper, a veteran travel guide, and a smart all-round assistant… For many families today, cars are no longer just "emotionless" means of transportation, but have been given more significance in the day and night.

In response to user enthusiasm, on the day of the launch of E8, GAC Trumpchi simultaneously announced the E8 full love preferred plan: 150,000 yuan, drive the car home! The quadruple gift broke the pain points of new energy car purchase and made China’s most "home" MPV within reach. Before December 9, through the GAC Trumpchi APP, GAC Trumpchi Mini Program, Trumpchi Smart Mini Program to order E8, you can also participate in the blind box activity, have the opportunity to win 10g BRICS.

With its outstanding performance and value-added price policy, Trumpchi New Energy E8 has redefined the most preferred household MPV with its strength. It is believed that in the Chinese household car market, it will set off a new round of enthusiasm.

Is the content suspected of violating the rules? The little red book was suddenly removed from the shelf, and there has been controversy in the past five months.

  Zhongxin Jingwei Client July 30th (Chang Tao) "Little Red Book ‘ Water inverse ’ Haven’t left yet. " On the morning of 30th, after seeing the news that "Little Red Book was suspected to have been removed from the shelves by major Android app stores" posted on Weibo Hot Search, senior user Xiaoyu (pseudonym) quipped in the comment area.

  The Sino-Singapore Jingwei client search found that as of press time, the Little Red Book App could not be downloaded and installed in the Android mobile app mall including Huawei, vivo, OPPO, Yijia and Xiaomi, and the Android mobile phone management software pea pods, Kuan and AppBao. However, the Apple App Store can still search for Little Red Books and download them normally.

  Little Red Book has been controversial in the past five months since it was exposed that "planting grass" notes were written and data was falsified on the eve of 315 this year. According to the ranking of complaints in the first half of 2019 published by Shanghai Consumer Protection Committee on the 29th, the number of complaints from Xiaohongshu exceeded 1,000, ranking in the top ten.

  Being removed from the platform by multiple platforms, the official response is "communicating"

  Zhongxin Jingwei noticed that when searching for "Little Red Book" in the app stores of vivo, OPPO and Xiaomi, the page showed "internal optimization, download is not available for the time being", while in Huawei’s app store, it showed "service adjustment".

  On the morning of the 30 th, the relevant person in charge of Xiaohongshu responded to the media that the product was suspected to be removed from the shelf. The company has learned about the situation and is actively communicating with relevant departments to solve it. Users who have installed Xiaohongshu App will not be affected in normal use.

  In fact, the sudden removal of products from the shelves is not "exclusive" to Xiaohongshu, which has happened to apps such as bilibili and Netease Cloud Music before.

  In July, 2018, bilibili was suspected of being taken off the shelves by some application stores, and it was later confirmed that eight video applications, including bilibili and Second Shot, were required to be taken off the shelves for one month in the centralized rectification action of the short video industry on the Internet. Since then, bilibili officials have issued a "comprehensive content rectification" announcement, saying that the content of the whole station will be rectified in strict accordance with the requirements, and the construction of the website audit team will be strengthened, and users will be mobilized to conduct self-examination and self-cleaning on the content and community.

  On June 29th, Netease Cloud Music, Himalayan and other online audio applications were removed from major app stores. On July 28th, Netease Cloud Music resumed its shelves in the Apple App Store.

  Some analysts believe that the reason why Xiaohongshu was removed from the shelves this time may be similar to that of bilibili and Netease Cloud Music: the content was suspected of violating the rules and should be removed for rectification at the request of the regulatory authorities.

  Controversial 5 months: note fraud, tobacco advertising, selling illegal drugs.

  According to the data, Xiaohongshu was established in 2013. It is the mainstream "content+e-commerce" platform at present, and it is also a "planting artifact" for many young consumers. Xiaohongshu officially disclosed that it has 250 million users and 85 million monthly activities. According to TheInformation, Xiaohongshu is currently negotiating financing of up to 500 million US dollars, and its valuation may reach 6 billion US dollars.

  Xiaohongshu has attracted much attention due to its rapid growth in the past two years, but at the same time, various chaos has quietly bred in the platform. Especially since March this year, Xiaohongshu has been in dispute.

  On the eve of 315 this year, the Sino-Singapore Jingwei client reported the "Little Red Book Planting Grass Notes Industry Chain". The survey found that the notes that made consumers crazy about "planting grass" on the Little Red Book platform may not come from the personal experience of real users, but were "fabricated" by professional writers according to the needs of businesses.

  In April, according to media reports, more than 90,000 tobacco soft articles appeared on the platform of Little Red Book. Later, Xiaohongshu announced that all the notes referring to tobacco were offline.

  In May, Xiaohongshu pointed the gun at the platform KOL (Key Opinion Leader): bloggers with less than 5,000 fans and less than 10,000 average notes in the past month will be disqualified as brand partners, and they will not be able to receive advertisements on the platform. According to media reports, under the new regulations, about one-third of the little red books KOL are affected.

  However, the survey of Sino-Singapore Jingwei client found that in less than a week after Xiaohongshu released this new regulation, a third-party brushing agency said that they could help KOL who failed to meet the standard to increase the exposure of notes and increase the number of fans. At the same time, some advertising public relations and brushing agency personnel also revealed that after the platform raised the entry threshold for brand partners, some Kols that met the standards started to sit on the ground and raised their own cooperation prices.

  Subsequently, Xiaohongshu began to strengthen the user evaluation system. On May 27th, Xiaohongshu announced the launch of the "Little Red Heart" scoring system, introducing the "one person, one vote" scoring mechanism, and all the scores were anonymous.

  Some insiders analyzed that Xiaohongshu’s adjustment is to save the trust crisis of the platform on the one hand, and pave the way for further commercialization on the other hand.

  In fact, in addition to e-commerce, on the road of commercialization, Xiaohongshu continues to explore. In June this year, Xiaohongshu requested to sign the Detailed Rules for the Management of Xiaohongshu Cooperative Organizations with MCN (a business model that produces professional content through online celebrity’s economic operation), one of which required the resident organizations to pay a deposit of 200,000 yuan. Subsequently, this clause raised questions.

  On July 27th, according to the Southern Metropolis Daily, there were still some illegal phenomena in Xiaohongshu App, such as Wechat business openly posting and displaying the sale of prohibited drugs in the country, recommending drainage to offline unqualified medical institutions and visiting doctors in the name of "planting grass", and even taking a lot of notes on the training course of "Amway" learning micro-plastic surgery on the 5th.

  In addition, the Zhongxin Jingwei client combed and found that in July, Xiaohongshu was successively named by the regulatory authorities.

  On July 2nd, WeChat official account, the official WeChat of the Ministry of Industry and Information Technology, reported the telecom service quality in the first quarter of this year. According to the report, the operating entity of Xiaohongshu, Hangyin Information Technology (Shanghai) Co., Ltd. (hereinafter referred to as "Hangyin Information Technology") has two problems involving users’ personal information, namely, collecting personal information without users’ consent and misleading users to agree to collect and use personal information. The Ministry of Industry and Information Technology said that it had ordered relevant enterprises, including Hangyin Information Technology, to rectify. (Zhongxin Jingwei APP)

Wait for what you want! The new BYD Han exposure comes standard with variable damping suspension?

Recently, some media revealed that BYD’s Han EV will launch 2023 Genesis models in the near future, and the new car is expected to be listed in early March.

As a modified model, the new car will be upgraded in four aspects: appearance, comfort, chassis performance and intelligence. It is expected that the overall product strength will be improved.

In terms of appearance, the new car will be consistent with the current models in general design. Bright chrome trim strips connected with the narrow and sharp headlights on both sides are common designs of many BYD models, which create a lot of simple atmosphere with the segmented lower enclosure with lower ventilation grille and air guide and the slender and low front.

At the same time, the 506/605km version of the Han EV model that is currently on sale will be upgraded to the Genesis version, and the appearance of the overall car system will remain unified. In addition, the new car will also add a brand-new glacier blue color scheme, and the visual experience will be more advanced.

In terms of interior, the new car will also continue the design layout of the current model. The new car will be equipped with an embracing cockpit design, a dual-frame multi-function steering wheel, an electronic gear lever of "Heart of the Dragon Engine", a 12.3-inch full LCD instrument and a rotatable 15.6-inch suspended central control panel, which is decorated with piano paint trim panels and chrome trim strips. The overall texture is good for many luxury brands of the same level.

In terms of configuration, the new car will be equipped with ambient light, heat pump air conditioner, 5G car, Apple NFC car key, etc. Some models will also upgrade the BSD blind spot monitoring system and other functional configurations, while the flagship model will add steering wheel heating, and the distinguished model will add Dana audio and other configurations.

In terms of power, it is expected that the new car will remain unchanged, and it will provide single-motor front drive and front and rear dual-motor four-wheel drive options. As a reference, the maximum output power of the single-motor model of the current model is 163/180kW, the comprehensive output power of the dual-motor model is 380kW, and the zero-hundred acceleration takes only 3.9 seconds.

In terms of endurance, the new car is equipped with a Ferrous lithium phosphate blade battery pack with a capacity of 64.8/76.9/85.4kWh. The cruising range is 506km, 605km, 610km and 715km respectively, which allows many users to choose according to their own needs and meets the needs of most consumers for medium and long-distance travel.

In addition, in terms of chassis configuration, the new car will also come standard with aluminum alloy suspension, the two-wheel drive version will come standard with FSD variable damping suspension, and the flagship model will also provide DiSus-C intelligent electronic control active suspension configuration options.

There are many substantial improvements in the configuration of the new model after this change, which will also make its comprehensive products more powerful in by going up one flight of stairs, and its cost performance is much higher than that of the old model. If friends have the idea of considering starting, they may wish to wait until the new model is listed before making a choice.

The first performance test of Zhiji L7, what Porsche is this level?

Zhiji L7 Angel Wheel will be delivered in the first quarter of next year at the earliest, and the interior of Zhiji L7 will be officially made public at the upcoming Guangzhou Auto Show. This new electric luxury brand, which was established only one year ago, is accelerating its way to people with a speed that exceeds that of any previous car companies.

This time, we got a close look at the excellent performance of Zhiji L7. Although it is still an engineering vehicle, the mechanical hardware and adjustment of the vehicle have been locked. In a word, it is a product with performance comparable to that of a million-level high-end luxury car, and it is the most fun car in the history of SAIC.

In a test field, the ground was printed with black marks left by the friction between the tire and the ground after drifting in circles. A senior technician said that this is the first time that a performance car has left its mark since the test site was put into use, and this mark was left by Zhiji L7.

What kind of performance car has Zhiji built? The authoritative data measured by this group of national motor vehicle product quality inspection and testing centers can make you better understand.

The acceleration of 3.87 seconds, the braking performance of 32.69 meters and the steady-state maximum lateral acceleration of 0.968G can be seen in the video at the beginning of the article.

In addition to the official measured data, there are also excellent performance, such as more than 10 consecutive full-power ejection starts, 50: 50 front and rear car body weight ratio, 0-100% real-time dynamic intelligent adjustment of front and rear axle torque, 100% kinetic energy recovery efficiency and 10.8m turning diameter. Any one of these achievements is worth talking about a lot, and the space problem is only briefly discussed from two hardware modules: motor and brake.

Heat dissipation is a systematic project for electric drive, and it is also one of the most difficult problems to solve. At present, the common practices in the industry are oil cooling heat dissipation, flat wire winding and motor thermal management system. Zhiji L7 has brought in a "Ao Bai" family bucket, and collected these mainstream schemes.

Compared with Tesla’s winding end oil cooling scheme, Zhiji L7′ s straight waterfall oil cooling structure can cool the winding end and core at the same time, which improves the sustainability by 46% compared with the current mainstream water cooling scheme. This innovative motor cooling structure has been applied for an international patent.

In addition, this motor also uses 8 layers of Hair-pin flat wire winding, which is simply to change the original round winding wire into a winding wire with a flat rectangular cross section. This has many advantages, for example, lines can be closely attached to each other, which improves the slot full rate and brings about the improvement of the overall power density of the motor. It can be understood that in the same refrigerator, you must pack more Wangzai milk in square cartons than in round cans, so that your refrigerator utilization rate will be higher.

For heat dissipation, the larger the cross-sectional area of the flat wire in the same space, the smaller the resistance, and the less the heat generated. In addition, the flat wire has a larger heat dissipation contact surface, which can achieve excellent heat dissipation effect with oil cooling. This is easier to understand, and your cooking is also cut into squares as much as possible, rather than columns, because the contact area is larger, which is conducive to heat conduction.

In addition to the hardware, Zhiji L7′ s motor cooling is also equipped with a thermal management system, which intelligently controls the electronic oil pump through algorithms, and sprays wherever it is too hot. Because the local temperature of the motor will be different under different working conditions, with the algorithm blessing, the heat dissipation can be done more accurately.

Why does Zhiji L7 have to work hard to maximize heat dissipation? Because Zhiji wants too much, he wants small size, high power, good performance, good HVH and low energy consumption.

Fortunately, although the design requirements are harsh, the engineers still meet them one by one. The high-efficiency and high-power permanent magnet synchronous motor mounted on the rear axle of Zhiji L7 solves the heat dissipation problem, achieves the same high performance as asynchronous induction motor, and gives full play to the advantages of small size, good NVH and low energy consumption of permanent magnet synchronous motor.

Thanks to this design, Zhiji L7 can not only achieve dual-motor four-wheel drive, but also break 100 in 3.87 seconds. It can also keep the front of the car in a low posture, and achieve an ultra-low drag coefficient of 0.21Cd. At the same time, with the mute design, the mute level is 3~6dB ahead of the industry.

The braking distance of 32.69 meters is largely due to the customized bembo braking system, including high-performance four-piston all-aluminum calipers and customized large-size high-performance brake discs. Many models only use brembo’s calipers and don’t buy brake discs. They also use brembo to support the scene, and there is little "Ao Bai" like Zhiji L7.

The size of the high-performance ventilation disc of Zhiji L7 is 365mm before and 356mm after, which has reached the level of a million-class performance vehicle. The larger braking friction area can bring better braking response and extremely low thermal attenuation.

In addition to performance, Zhiji L7 also gives consideration to energy efficiency. Zhiji L7 also uses the Onebox fully decoupled brake control system provided by Continental. At present, the mainstream scheme on the market is Twobox system, and the mechanical braking and regenerative braking can’t be decoupled. The intuitive feeling is that when the assisted driving is enabled, the ACC system controls the acceleration and deceleration, and your brake pedal will follow. If the AEB system is enabled, it just happens that your foot is under the brake pedal, and you will probably go to the hospital to hang the orthopedics.

The influence of Twobox system on energy consumption lies in that when you step on the brake, mechanical braking will definitely step in and consume part of kinetic energy, while the rest will flow into the kinetic energy recovery system, and the recovery efficiency is only 60%-70%. Onebox fully decoupled braking control system, when stepping on the brake, can completely rely on kinetic energy recovery to achieve deceleration when the deceleration is less than 0.3 g, and the mechanical braking part will only intervene when it exceeds 0.3 g, so that 100% kinetic energy can be recovered, and it can be called Lu Hua peanut oil-squeezing expert in kinetic energy recovery field. In addition, the Onebox fully decoupled brake control system can realize more flexible adjustment of the brake pedal and provide redundant braking for high-level intelligent driving.

As said in the video, Zhiji L7 reveals an ultimate pursuit of perfection, which is very difficult for such a complex product as intelligent electric vehicle.

The high-level assisted driving realized by the large computing chip and lidar, the liftable screen and 22 speakers create an intelligent cockpit with the ultimate sense of science and technology, and the driving performance that can be rushed out, braked firmly and manipulated flexibly. Zhiji’s pursuit for the ultimate is far more than that.

The paranoid pursuit of perfect quality can promote the perfect integration of scientific and technological progress and user experience. Perfection is difficult, but we can see that Zhizhi is already on the way to perfection.

Focus on the changes of college students’ consumption: the essential items have changed from lunch boxes to mobile phones and computers.

  BEIJING, Beijing, August 23 (Reporter Zhang Ni) Recently, a prospective college student in Zhejiang suspected that the monthly living expenses were less than 1,200 yuan, which caused a heated discussion. Many netizens felt that "the cost of raising a college student is too high now!"

  From reporting to school with a kettle washbasin on his back in 1980s, to now, mobile phones, laptops and iPad have become the standard for freshmen. In the past few decades, the "entrance equipment" of college students in China has undergone earth-shaking changes, and the improvement of material conditions has witnessed the development and changes of the times. However, the increasingly obvious trend of comparison in university campuses has also caused people to think.

  Entered school in 1989

  — — Necessary is your own lunch box.

  In 1989, Yang Jinsong, a young man from Guiyang, was admitted to Northwest Institute of Light Industry (now Shaanxi University of Science and Technology) and went abroad to study.

  Recalling his college days, he said with a smile: "Life at that time was extremely simple, and the necessary thing for admission was his own lunch box, because there was no public tableware in the canteen."

  Yang Jinsong told reporters that in those days, his living expenses were provided by his family, and he sent them to 80 yuan at home for one month, mainly for eating, and a small amount was used to buy books, daily necessities, etc. Basically, there was no off-campus entertainment expenses.

  "In memory, at that time, everyone was very frugal. In addition to learning utensils, they were unable to purchase other items. A few families with good conditions have walkmen or guitars. " Yang Jinsong said.

  During college, Yang Jinsong and his classmates played poker as a pastime, which basically cost nothing. He and his classmates occasionally traveled around together, which was also a poor tour. There were few cameras and basically no commemorative photos.

  "It was not popular to go out to eat in those days, because there was no money, and everyone was honestly eating the canteen. Most students usually eat 4 cents of food when they are cooking, and they dare to eat meat once a week with a little diced meat, and a piece of sauce beef costs 8 cents! "

  In terms of learning, in those days, tapes and books were very precious to Yang Jinsong and his classmates. Everyone would cherish them and listen and read them seriously.

  "Silly, but very real, life is very thick, and I still feel nostalgic after the aftertaste." In Yang Jinsong’s view, the biggest difference between the life of college students now and before is that the material conditions have been greatly improved, and children have little sense of thrift and early self-reliance.

  "In our time, we basically had to stand on our own feet immediately after graduation and no longer spend money at home. In addition to the basic living expenses, you rarely get extra money for entertainment and other consumption. Every time you go home on holiday, you have to buy a hard seat ticket, which takes 30 hours. " Yang Jinsong said that hard-working exercise is particularly beneficial.

  Entered school in 1998

  — — The communication tool is a BP machine

  In 1998, Li Min (pseudonym) entered a university in Zhejiang to study business administration. As a college student in the 1990s, Li Min’s college life was much more comfortable at that time. As far as she can remember, the monthly living expenses were about 800 yuan, which were mainly used for eating and dressing, and the entertainment items were very limited.

  "We reported to school with our daily necessities at that time, and there was nothing else." Li Min recalled that at that time, mobile phones were not popular, and there were no electronic devices. After he went to college, he bought a BP machine as a communication tool. At that time, learning English was also listening to tapes, so it would be nice to have a repeater or Walkman.

  In the late 1990s, computers were not popular in colleges and universities, and online games and social software were not popular in schools. Li Min said that at that time, he was more focused on his studies, didn’t go out to play much, and spent most of his time studying.

  "At that time, among the living expenses given by my parents, I had to find a way to save some for buying study materials and for some exams." She recalled that in college, students’ living expenses were basically provided by their families. Few people worked part-time to earn money, and there were few opportunities, and everyone didn’t have that consciousness.

  In Li Min’s view, the comparison atmosphere in the school was not obvious. Students didn’t rush to pursue something, and life was simple.

  Entered school in 2003

  — — 10 yuan money can be eaten well in the canteen every day.

  In 2003, Li Honghan entered Zhengzhou University to study. Recalling the scene of going to college more than ten years ago, he told reporters that many students around him were still relatively poor.

  "Eating in the canteen is also very cheap. You can eat well for less than 10 yuan a day, plus the extra expenses of buying daily necessities. At that time, the living expenses of four or five hundred yuan a month will be enough." Li Honghan said that when he was at school, he could still receive a state subsidy of 50 to 60 yuan every month. In those days, the money was not too small, and he was very happy every time he handed it out.

  "When I first went to college, mobile phones were not fully popular, and there were no smart phones. I remember that my first mobile phone was bought in 2007, and it was a Nokia bar phone." Li Honghan recalled that when he first entered school, everyone bought calling cards and contacted family and friends by telephone. The monthly communication expenses were not much.

  "At that time, there was very little human expenditure, because everyone was a poor student. I felt very happy to have a meal together in the canteen. I didn’t say that I would go out every day. You invited me to invite you. Although I was poor, I was also very happy. This is our true life portrayal at that time." Li Honghan said.

  When he was in college, Li Honghan’s first extra income was the money he earned as a tutor in his senior year. He was good at writing, and since then he has contributed to many newspapers and magazines, earning remuneration for his contribution. Although his income seems to be not much now, it was enough to make him feel excited and happy as a student at that time.

  "I have been educated since childhood to be sensible and obedient as much as possible, and not to add too much burden to my parents, so I have always lived within my means and will not reach out to my parents in pursuit of some material enjoyment." Li Honghan said.

  Admission in 2014

  — — College students use Apple mobile phones.

  Wang Jiazhen, born in 1996, entered the journalism major of Suzhou University three years ago. As a "post-95" college student, the living and learning conditions of Wang Jiazhen and his classmates have changed greatly.

  At the beginning of her freshman year, Wang Jiazhen’s parents bought her a mobile phone and a computer, which are common among her classmates at present.

  Wang Jiazhen said that his monthly living expenses are about 1,500 to 2,000 yuan, which is the average level in the class. "Eating accounts for the most of these expenses, and it costs about six or seven hundred yuan a month. The rest of the expenses include transportation, telephone bills, clothes and so on."

  She told reporters that in addition to the necessary expenses for food and clothing, college students nowadays also have some personal expenses. Students occasionally eat out, and many students who are in love even send gifts to each other on festivals such as Chinese Valentine’s Day and Valentine’s Day. She quipped: "Students who are not in love at this time can save a lot of money!"

  In Wang Jiazhen’s view, in the past few years, I have also felt that the comparison atmosphere in the school is relatively heavy. Everyone likes to compare the quality of mobile phones and cosmetics, and many people have used Apple phones.

  "In fact, I think this should be based on personal needs. Not everything is the most expensive, so it is best. You can choose something better if you have the conditions, but you should do what you can." Wang Jiazhen told reporters that she will also earn money through part-time jobs now, and if there is something that needs to be bought, she should talk to her parents as little as possible.

  "Nowadays, there are many opportunities for college students to work outside. I have done a lot myself, including training institution teachers, moderators, recording, etc. The school will also have scholarships. It is not a small income to save one." Wang Jiazhen told reporters that in recent years, she has also gained something through her own efforts. Now she has exchanged the money she earned for a computer and an Apple mobile phone, and bought a micro-single for completing professional homework, which makes her feel very fulfilled.
