If China invents everything before foreigners, why is China still a developing country?

Developing countries are a very general concept in their own right. It should be said that until today, there has not been an accurate and unified system in the world.

1. A generally accepted scientific definition of developing countries. The United Nations has explicitly identified 49 countries as least developed countries. Developed countries, on the other hand, have established themselves as developed countries by committing to more international obligations or by not seeking certain special treatment.

There is an international consensus that a country is considered economically developed once it joins the Organisation for Economic Co-operation and Development (OECD), but with the accession of some developing countries with good development performance, such as Mexico and South Korea, this consensus has become difficult to grasp in practice.

At the same time, China and other underdeveloped countries have the same characteristics, that is, they have a large territory, a large population, and a small per capita GDP. However, in this day and age, no one is talking too much about it, as if it were just a conventional, just thinking about the name. The landlord should not pay too much attention to it, now the emphasis is on the strong and international competitiveness of the group.

Developed countries, developing countries, all just a name!

IMHO, the Chinese can't talk about the word "smart" at all. China invented first only because civilization was established relatively early, but its development has always been slower than that of Europe, the United States and Japan.

There is competition to develop,,, it should be said that before the Qing Dynasty, the ancient civilization was higher than the West, since the implementation of the Kangxi lockdown, resulting in no competitiveness, and other countries are not in line with the other,,, we are more than 200 years behind, the world should be interactive

Hey, it's all because of China's backwardness in modern times, and then it was beaten and robbed, resulting in a weak foundation for development after the founding of New China.

Although developing countries themselves do not represent anything, it is obvious to all that China cannot be at the forefront of its comprehensive national strength today. If you want to say the reason, it is not clear in a few words. However, when it comes to the status of ancient China in the world, it was always a leader before the Kangqian era of the Qing Dynasty (including Kangqian).

But it won't work in the later stage, and the long-term avoidance of self-defense eventually caused Yelang to be arrogant.

Because the motherland is now compromising on everything.

The things invented by the Chinese are:

1. Paper Cai Lun, a eunuch of the Eastern Han Dynasty. Using tree bark, broken fishing nets, rags, hemp and other raw materials to make plant fiber paper suitable for writing. He was named the Marquis of Longting by Emperor He, and was called Cai Hou Paper.

2. Movable type printing Bi Sheng, Northern Song Dynasty Hubei Yingshan cloth clothes. According to Shen Kuo's "Dream Creek Pen Talk", it is engraved on the clay sheet, one word is printed, and it becomes a movable type after being burned hard. It can be printed on ink and paper, and the movable type can be removed after baking, and it can be reused.

3. Loom Huang Daopo, a native of Shanghai at the end of the Southern Song Dynasty, was born as a child daughter-in-law. He learned textile technology from Li Min in Yaxian County, Hainan, and returned to his hometown to reform cotton spinning tools, including seeding and churning, cotton vertebral arches, and three-spindle pedal spinning wheels.

4. Hydraulic blower Du Shi, Nanyang Taishou of the Eastern Han Dynasty. The water drain is powered by water, and the leather blower bag is continuously opened and closed through a rolling machine, and the air is sent into the iron-smelting furnace, which is called "Du Shi water drain", the world's earliest hydraulic blower.

5. Mahjong is difficult to test. One illustrates the eunuch Zheng He, enriching the life of sailors who went abroad; Second, it explains that the beginning of Wan Bingji, a metaphor for the heroes of Liangshan; The three said that it originated in Taicang, Jiangsu, and was rewarded with a number of cards. The earliest record of mahjong is the "Mahjong Sutra" of Yang Danian in the Song Dynasty, and the Qing dynasty Chen Shimen was rich and developed.

6, match Northern Qi palace maid. According to Tao Gu's "Qing Yilu", in 577, the Northern Qi Dynasty was attacked on both sides, lacking fire to cook and keep warm, and in despair, a group of poor palace maids magically invented matches and made them of sulfur.

7. The abacus is difficult to test, and it is a calculation plan at the beginning. One said that Liu Hong, an astronomer of the Eastern Han Dynasty, created the "Dry Elephant Calendar" and personally taught it to Xu Yue, and Xu's "Records of Mathematics" recorded the style of the abacus for the first time; Second, Liu Hong learned from the Taoist Mr. Tianmu and taught the method of abacus; The name of the three said abacus was first seen in the Yuan scholar Liu Yin's "Collected Works of Mr. Jingxiu".

8. Small hole imaging Mozi, Doctor Song, representative of the pre-Qin Mo family. Mozi discusses the balance of levers, and does the world's first experiment on the formation of inverted images of small holes, explains the reasons for the inverted images of small holes, and points out the nature of the linear progression of light. This is the first scientific explanation of the linear propagation of light.

9. Compass Shen Kuo, a scientist of the Song Dynasty. Sinan was invented during the Warring States period, and Shen Kuo's "Mengxi Pen Talk" further explained the method of making a compass by magnetizing an iron needle.

10, Surveying the Garden Sea Mirror Li Zhi, a mathematician of the Song and Yuan dynasties, "Surveying the Garden Sea Mirror" is the first giant book to retell the "Tianyuan Technique".

There are many Zen envy and filial piety, but now list the situation that most people have:

1.Smartphones. In the early days, mobile phones only had the function of calling and texting, and many people did not think that it could be used for entertainment and lifestyle. But with the rise of smartphones, it has become an indispensable and important tool in most people's lives and work, and it is a fact that it is inseparable from it.

2.Online shopping. At the beginning of the congratulatory draft, many people were wary of online shopping, feeling that they could not see the products directly, which was not safe and reliable. However, with the development of e-commerce, online shopping has become a common way of consumption, and it is also an important choice for many people to avoid crowded shopping environments.

3.Social networks. Initially, many people thought that social networks were just a stuff for young people and had no practical use.

However, with the acceleration of people's life pace and social connection, social networks have gradually become an important platform for people's social life and access to information, and many people cannot do without it.

4.Bike sharing. When it first appeared, many people were also skeptical about bike-sharing, believing that it was not safe and hygienic.

However, with the development of the market, it has gradually become an important means to solve short-distance travel, and it has also had an important impact on the daily life of many urban residents, and it has been inseparable from it.

In general, in the early days of technology and products, people tend to look down on them due to unfamiliarity and insecurity, but as the actual value they bring is continuously verified in life, this perception and psychology will also undergo important changes, and eventually cannot be separated from them. A lot depends on people's experience and changing habits.

Needless to say, the four major inventions are needless to say.

In addition, there are:

Timers, bridge, saddles.

Lunisolar calendar. The world's oldest star catalog, the Shi's catalog.

An instrument for demonstrating celestial visual motion, the armillary sphere.

The oldest time-keeping instrument in our country - pot leakage.

Zhang Heng's geokinetic instrument.

Calendar Revolution - Shen Kuo's "Twelve Qi Calendar".

Keyuan Wonder - an astronomical instrument invented and developed by Guo Shoujing.

Zu Chongzhi and Pi.

Abacus. Magnetic Kai pure declination and magnetic inclination.

Measuring tool – vernier caliper.

Projection slide show – marquee.

Bamboo and wooden tablets.

Silk books and paintings.

Silk mold Sunzhou cotton paper - Hehoof.

The world's first vegetative fiber paper.

The equatorial instrument of Han Dai Luo Xia Hong.

Su Song - Chinese astronomer of the Song Dynasty. In cooperation with Han Gonglian, he made a planetarium and a water transport instrument elephant platform, which was the first planetarium in ancient China.

Ma Jun, a native of Wei, invented the water keel car.

Ding Xuan (Han Dynasty) invented the incense burner, the lamp, and the rotating fan.

Du Shi pioneered the water discharge of hydraulic blast equipment. That is, the use of water to push the fan to blow air. It was the world's first hydro-powered blower, 1100 years ahead of Europe.
