Why did China's ancient science and technology stagnate after the Ming and Qing Dynasties? Answer according to five historical facts.

One is the problem of social and cultural traditions and intellectual values, and the other is the problem of philosophical thinking mode. In terms of political economy, China's long-term feudal economy resulted in a self-sufficient economy that ignored the concept of businessmen and failed to open up markets, especially overseas markets, which made China's productivity not develop on a large scale, so there was no market force to promote the development of science and technology. Lack of labor demand will have the motivation to develop machines, but China did not have such demand, so it missed the opportunity of the first industrial revolution.

Feudal rulers did not attach importance to science and technology, thinking it was a small skill and disdaining publicity and promotion. Not only can scientific knowledge not be popularized, but also scientific methods and scientific spirit cannot become a common practice.

In addition, he thought highly of himself at that time and regarded himself as the center of the world. He thinks that China's culture is the highest in the world, so he is unwilling to absorb foreign advanced technology and culture. At the end of the Ming Dynasty, there was a famous doctor named Yang Guangxian. At that time, Chongzhen wanted a German to help make the calendar, because China's calendar was not very accurate. Yang Guangxian objected that he would rather have no good calendar in midsummer than foreigners in midsummer. Rejecting western culture and technology, even if the Westernization School in the late Qing Dynasty wanted to introduce western technology based on China sports, it was actually a bit absurd. ?
