The famous emperor Gao Xin Shao Hao was born in Gao Xin. He is the grandson of Xuanyuan Huangdi and the son of Gao Xin Di Ku. In folk mythology, Shao Hao bird is a golden phoenix, which was raised by the mother of Shao Hao bird flying in the East China Sea. When it grew up, Shao Hao Bird became the White Emperor, that is, the emperor of the West.
Xiao Yao is an apprentice of Gao Xin Shao Hao. She was exiled to the people for the murder of Lord Xuan Lang, and was adopted and accepted as an apprentice by Gao Xin Shao Hao. In order to protect Xiaoyao's safety, Gao Xin Shaohao took a series of measures, including deleting her from the official records and arranging for her to live in Xiushe City. Xiao Yao also doesn't know his true identity because of these measures.
If you are interested in the reason why Shao Hao excluded Xiao Yao from the music score, I suggest you consult relevant historical documents or consult relevant historians to get more accurate information.
