What influence did the eclipse have on Fengshui in the Han Dynasty?

In the long-term astronomical observations of the ancients in our country, it was discovered that the sun travels through a circular path in the sky every year. The ancients called this path the "ecliptic". In fact, it is the projection of the sun on the earth when the earth revolves. The sun revolves along the ecliptic on the earth once a year. In order to facilitate the determination of the specific position of the sun, people divide the ecliptic into twelve equal parts (each equal part is 30.), named after a nearby constellation, these constellations are Called the zodiac sign.

The stars on the zodiac were divided into 28 constellations by the ancients, called "twenty-eight constellations", and divided them into four houses of east, south, west, and north. Each house has seven constellations. Zhuque and Xuanwu are the names of the four palaces. Feng Shui has used the concepts of Zuo Qinglong, Right White Tiger, Qian Suzaku, and Right Xuanwu to this day.

In the Han Dynasty, people invented the method of choosing auspicious days according to the ecliptic, that is, "selecting auspiciousness".
