After the dissolution of the Jesuits, Qin Tianjian was successively succeeded by messengers such as Ferreira, Ray Beriau, Pires and Qian. In the seventeenth year of Daoguang, Qian resigned and returned to the west. Since then, Qin has stopped using westerners.
The National Astronomical Observatory in ancient China was responsible for observing astronomical phenomena and promulgating calendars. Qin Zheng is equivalent to the director of the National Astronomical Observatory. Because the calendar is related to agricultural time, and the ancients thought that the astronomical phenomena and personnel changes are directly corresponding, so Qin Tian's position as a supervisor of the country is very important. The calculation method of calendar used in Ming dynasty had a big error, which was not conducive to the rule of the dynasty. Just then, the missionary brought a new calendar.
Established in the early Ming Dynasty, it was renamed Qin, with officials such as supervisor and deputy supervisor, and western missionaries participated in the work at the end of the year. In the Qing Dynasty, the management supervisor was a senior official, and the supervisor and deputy supervisor were both from China and Manchu, with the participation of western missionaries. At the beginning of Qianlong, the deputy supervisors were divided into Manchu, Chinese and Western. After that, Huaxi people either returned or died, and no outsiders were needed to enter the official.
