Why are there so few natural scientists in ancient China, including modern ones?

In ancient times, there were not many natural scientists, whether in China or abroad. Astronomy is the earliest beginning, which is the need of human survival. The Arabian Nights is usually associated with astrology. With the development of astronomy, mathematics came into being. These two disciplines developed earlier. China has the best astronomers and mathematicians in the world.

Now there are many natural scientists in China, but China still puts the greatest energy into applied science, so he thinks that there are few natural scientists, but in fact, from the total number, the number is also very large, and he has made many achievements.
