You said China ruled from Qin Shihuang to Qing Dynasty! Why are foreigners good at inventing things so early? What is concession?

Most of China's traditional skills were handed down from master to apprentice, which was easy to be lost, because he followed the ancestral teachings that were not open to outsiders. Moreover, the social status of ancient developers is low, which is considered as "strange skills and cunning".

Western science is based on experiments from a rational point of view, and most scientists come from noble and jazz backgrounds. Because of their hobbies, they get together to further promote scientific and technological progress.

So the gap is getting bigger and bigger. I recommend two books:

The Commercial Press of History of Western Science by Anthony M. alito.

The Origin of Western Science by David Lindbergh China Foreign Translation Publishing Company
