Who is the author of the astronomical achievement "Wanli" in Yuan Dynasty?

In Song Dynasty (96 1 year), Ma Yi, the ancestor of Anhui Hui horse history, came to China from the western regions at the invitation of Song Gaozong, compiled a new calendar to correct China's original calendar, and introduced the method of calculating the position of the zodiac and the date of the sun entering the palace in Arabic astrology into China astronomy. After more than two years, it was compiled in April 963. Tian Li consists of six volumes, including Shangshu, Calculation of Classic Prescriptions, Formation of the Ephemeris of Wugeng, Standing Day and Night, and Standing of the Sun Shadow. This is the first attempt to systematically introduce the Arabic calendar into China. During the Yuan Dynasty, the Ming Calendar of the Jin Dynasty was once used, but there were many errors between the calendar and the actual astronomical phenomena. In the fourth year of Yuan You, Jamalidin compiled the Perpetual Calendar with reference to the Arabic calendar, and submitted it to the Yuan government, which was approved and promulgated by Yuan Shizu. This calendar has been used in China society for 65,438+04 years.
