In ancient China, full-time civil servants were set up, specializing in "observing the image and choosing the time". In literature, excellent calendars, amazing inventions and insightful world views all occupy an important position in the history of world astronomy development. As early as the Yangshao culture period, people described the radiant image of the sun, and then recorded the changes on the sun, depicting the sun's edge as large as a projectile, showing an inclined sunspot. The ancient calendar in China includes not only the calculation of solar terms, the allocation of days per month, the arrangement of months and leap months, etc. It also includes many astronomical contents, such as the calculation and prediction of the occurrence time and visibility of solar and lunar eclipses, and the calculation and prediction of the positions of the five major planets.

If you want to get all these more than 400 astronomical almanac, please pay attention to the lower right corner of the picture.
