Does Zhouyi include astronomy?

Ancestor Fu looked up at astronomy and geography ... and began to draw gossip!

Sanyizhong: It's a magic number, focusing on observing the celestial phenomena and measuring the national fortune. Yes: Taiyi said tomorrow! The five elements of gold, wood, water, fire, earth and five stars correspond to the fire, water and earth in Jin Mu. For example, this year's "ugly" year was moved from Jupiter (the largest star among the nine planets) to the east of due north (ugly face) 15!

This is more reflected in the traditional geomantic omen, such as: Eight Houses (also known as nine planets Eight Doors) geomantic omen, southern Kong Xuan geomantic omen and so on. Among them, the "Nine Planets" come from the Big Dipper: Shu Tian, Tian Xuan, Tianqi, Tianquan, Yuheng, Kaiyang, Yaoguang plus Zuo Fu and Friendship!

In a word, the theory of Zhouyi is inextricably linked with astronomical knowledge. ......

However, there are some differences between the astronomical knowledge in Zhouyi and modern astronomical science in concept and application!

The astronomical knowledge in Zhouyi is the conclusion drawn by ancient sages through further understanding of things and rough observation and experience of astronomical phenomena. There is inevitably an element of idealism in this!

Modern astronomical science is basically seen by "eyes". There are data, formulas and theories, and the results obtained by step-by-step reasoning are more in line with the facts!
