Abstract
The Jin Dynasty’s astronomical calendar was established on the basis of the Liao and Northern Song dynasty. Its astronomical ruler was the same length as HeXian’s ruler in Northern Song, and one foot was about 24.5cm. The scale originated from the small rulers of Sui and Tang, and its influence was to ensure the length of the astronomical ruler remained unchanged for more than 1,200 years to Yuan and Ming Dynasty. And promoted the continuous development of the traditional astronomical calendar research.
