Why does the gate of Confucius Temple in China open from east to west? Didn't China's ancient geomantic omen talk about "sitting north facing south"?

Before the Qin dynasty, it was west facing east.

Why is the mausoleum of the First Qin Emperor from west to east?

The mausoleum of the First Qin Emperor is located 5 kilometers east of Lintong County, Shaanxi Province, south of Lishan 1 km, and north of Weishan. It was built in 246 BC and took 37 years to complete. It's very large. The existing site has a mound with a height of 47 meters and a circumference of 1, 4 10 meters. There are two cities around the mound, the inner city is nearly 4 kilometers and the outer city is about 6 kilometers. Most of the tombs of emperors in China face south to show that the south was king before his death and he would rule the world after his death. But at the beginning of the imperial tomb, it was strange to sit west and east. Why?

I think Qin Shihuang may have two ideas. First, he failed to find a prescription for immortality before his death, and he has been worried about this matter. He has made many tours, with Jieshi in the east and Huiji in the south, and the word Taishan. He yearned for the legendary fairy in the East China Sea, but many visits failed. Sending Xu Fu to lead 3000 boys and girls across the sea to the east, but there was no news, which made Qin Shihuang feel extremely disappointed, but he still hoped that his soul would ascend to heaven in the afterlife. Second, Qin is located in the west of the Seven Heroes in the Warring States Period. Ying Zheng designed his mausoleum to sit in the direction of west facing east, just to show his determination not to stop until he conquered the six eastern countries. Later, he unified the six countries and still built his mausoleum according to the original layout, in order to let his damn fool monitor the six countries in the East and prevent their restoration.

This is of course all speculation. The biggest possibility is related to the manners and customs between Qin and Han dynasties. "Book of Rites" said: "The proprietors should pay homage" is a ceremony; There is a description of Xiang Yu in Historical Records: "Wang Xiang and Xiang Bo sit in the east, Yafu in the south, Pei Gong in the north, and Sean in the west", which proves that it is fashionable for the host to sit in the east. At that time, from emperors, governors to generals to ordinary literati families, the owners all sat west to east. Qin Shihuang is the master of the world, and his residence will naturally face east after his death.
