Astronomical interpretation of remnant stars and upper stars

Quotient is the name of ancient stars in China. According to today's astronomical constellations, Canxing is Orion and Shangxing is Scorpio. Canxing is in the west and Shangxing is in the east. When one rises and the other sinks, they will never meet again.

Zuo Zhuan records that the two sons of King Gao Xin were at odds and fought every day. The Gao Xin family had no choice but to transfer the eldest son to Shangqiu, where Shangxingguan is located, and the younger son was transferred to Shangxingguan in the summer, so the two sons had no chance to meet and fight. "The meeting between friends is almost as difficult as the morning star." Are Scorpio and Orion in the sky? One is destined to release filariasis on a hot summer night, and the other is destined to shine cold light on a cold winter night. Even if one follows the footsteps of the other, one will always rise in the east and one will fall in the west, and there will always be an insurmountable sky in the middle.

The distance between the extended data quotient and the reference star in the sky is about 180. They rise and fall, and never appear in the sky at the same time. The poem "It is difficult for friends to meet each other like the stars in the morning and evening" written by Du Fu, a famous poet in the Tang Dynasty, comes from this. Because of its fiery red color, Antares was also called "fire" or "great morning" in ancient China.

The ancients watched Mars very much. They often determine their agricultural activities by the position of fire in the sky, just as the ancient Egyptians predicted the flood of the Nile by observing the position of Sirius in the sky. In China's ancient masterpiece The Book of Songs, there is a saying that "the fire will flow in July and clothes will be given in September". When the weather turns cold in July of the lunar calendar, you can see the big Mars falling from the west after dark. It's time to prepare warm clothes in September.
