Doujiu is one of the seven oriental basalts among the 28 stars, and the first northern basaltic star. Dou Su belongs to water, also known as Yi. Named after its constellation combination, the ancients also called the "Temple of Heaven" and belonged to the son of heaven. The star of the son of heaven, the average person is not easy to offend, so fierce. The meaning of fierce is not sinister, but its position can be impacted by fierce.

The integrity of Dousu is 180 degrees, and Dousu corresponds to Xuanwu King, Baihuxiang, Xuanwu Xiu and Suzaku Prison.

Dou Su has a star official named Dog Country. According to legend, in ancient times, Gao Xin's family in Di Ku was harassed by dogs, so he ordered that if any soldier took the head of an enemy chief, he would betroth his daughter to him. The words sound just fell and my dog Tiger Pan jumped out of the house and disappeared. A few months later, he came back with the head of the enemy leader in his mouth. Di Ku had no choice but to keep his promise and promise his dog and his government to build a country. This is the dog country. It is said that all the subjects in this country are descendants of the princess and Pan Hu. Women are people, men are dog faces. There are also rumors on the Internet that this dog Rong may have something to do with Egypt. Because of its long history, the answer should be given to future archaeologists. Another legend says that Gourong is a brave people who take dogs or wolves as their totem. In the Western Zhou Dynasty, in order to win the love princess's smile, he directed a farce of "playing princes by bonfire". Unexpectedly, the dog Rong tribe lost their hearts and entered the Haojiang River, which led to the relocation of the capital of the Zhou Dynasty to Luoyi and the opening of the war-torn Eastern Zhou Dynasty. It is recorded in the "Wan Yan Ge Ji" of the guest teacher that this dog Rong family should be the dog Qing family, after the family. Perhaps related to his clan, I believe the truth will surface in the future.
