Who was the nine sons of Beidou in Song Dynasty?

Shu Tian, Tian Xuan, Tianji, Tianquan, Yuheng, Kaiyang, Gou Jian and Wei Zi are the nine sons of Doulao.

Dum Yuan Jun has nine sons, seven of whom make up the Big Dipper. There are seven famous stars in the northern hemisphere, which is what we call the "Big Dipper". "The Big Dipper" played a great role in the production and life of the ancients.

Sima Qian described the function of the Big Dipper in Historical Records as follows: "The Big Dipper divides the yin and yang, making four seasons, and dividing the five elements equally, shifting degrees and setting the age." This shows how important the Big Dipper is in the eyes of the ancients.

The Great Han Emperor in the Arctic is the Great Han Emperor, and the Emperor Gouchen in the Palace is the Great Han Emperor Gouchen. Therefore, we can find a pair of brothers, namely the great emperor China and the great emperor Gou Jian of China, who are Yuan Jun's mothers.
