Studying in Wei Zi, the Sun Star is in Chen Gong, and the Moon Star is opposite Gonggong. Why is it called Youlong Gate? What does Youlong Gate mean?

Youlong Gate is the first time I've heard of it. . . The sun is in the morning and the moon is in the sky.

"Dangui Pavilion"-The sun lives in Chen Chen, the Moon lives in Xu Xu, and a life wall is built in Chen Chen or the garrison palace. The sun is in the third place and the moon is in the unitary position. Set up a wall of life in the third or unitary palace. There is an old saying: "Er Yao is always bright and just wins, and his talent and momentum will make him a hero. If a teenager succeeds, he will jump into Tianchi and become a dragon." 」

The sun obeyed orders and entered the temple, which the ancients called "Dan"; Taiyin obeyed his orders and entered the temple, which the ancients called "Guiyuan". In ancient times, the name of a family was valued rather than the wealth of businessmen, so it was considered that "Dan Yong" and "Gui Yong" were profitable and sought fame. Therefore, there is an old formula: "The sun watches at noon in Tatsumi, which is rich and brilliant". The sayings that "Taiyin is clear in water, clear in calyx, and loyal to admonition only when the land is clear" and "Tianmen is bright in the moon, and the Hou is sealed" all come from Sunju Temple in Taiyin.

But later generations are determined to find out the pattern of "two obsidians are always bright" in an attempt to add a little luster to the pattern. Therefore, in addition to the pattern of "the sun and the moon are bright" and "the sun and the moon must be bright", they also tried their best to find out the galaxy where the sun and the moon are located and shine on each other in the palace, becoming a pattern. And still use the names of "Dan Yong" and "Gui Yong".
