Qin weizi

Qin, also known as the name implies, was mainly responsible for observing the stars in the sky in ancient times. As we all know, China's ancient astrology theory can be said to be equivalent to metaphysics. Whenever something important happens, China and Sirius take turns, so the ancient astronomical knowledge is not systematic. These foreigners entered China and brought advanced and systematic astronomical knowledge, which shocked the emperors of the Qing Dynasty. Therefore, they will continue to reuse them.

A, Shunzhi red man Tang Ruowang The first foreigner in the Qing Dynasty and Qin Dynasty should be, especially famous in history. He brought not only astronomical knowledge at that time, but also medical and even scientific ideas, so the emperor shunzhi paid special attention to him at that time, but in the end, because Christianity expanded too fast, the Qing Dynasty gave up Tang Ruowang.

Second, Ferdinand ferdinand verbiest Compared with Tang Ruowang, Ferdinand ferdinand verbiest, the etiquette of Kangxi, is more proficient in astronomy. At that time, he helped Emperor Kangxi to write a book, Kangxi Li Yonglv, and even put forward the concept of China's Jingwei Road. Although it was not taken seriously at that time, it was an intergenerational progress in astronomy in the Qing Dynasty, but it was still because of Christianity. He was also afraid of the Qing court and finally died in Beijing.

Third, the astronomer Ignace Koehler Dai Jinxian came to the Qing Dynasty at the latest, but he also brought the most advanced technology. In the Qing dynasty, he wrote the total star map of the ecliptic. The main content of this book is to correct some mistakes in the star map before the Qing Dynasty, but his best book is another book, Li Kao, which was the most advanced in the world at that time. We can see who is quoted in this book.
