How did the name "Xuan" come from today? How did it develop?

The origin of Xuan surname "Xuan" surname is a rare surname in China today, but it is widely distributed. The origin of the surname Xuan can be traced back to the ancestor of Chinese culture, Huangdi, and its two origins are related to Huangdi: one is the descendant of Xuantao, the son of Huangdi, and the other is the descendant of Xuanshou, the courtier of Huangdi when he was a child. Historical Changes Check the names of China's "Xuan" in previous dynasties, all of which were born before the Song Dynasty: there was a mysterious custom in the Western Han Dynasty, and there was a famous doctor who was said to be invisible. He was appreciated by Hejian Wang and wanted to match his daughter, so he fled to Hengshan; Xuanhe was recommended by the famous minister Wu Lun in the Eastern Han Dynasty. He used to be the magistrate of Jiujiang, famous for his incorruptibility and strictness. Xuanlan in Nanqi was a famous political commentator at that time. After the Song Dynasty, Xuan's surname was changed to Yuan, which led to the decrease of Xuan's population. The reasons for changing the surname are taboo: First, in the Northern Song Dynasty, because his father was named, it was ordered that all people surnamed Xuan in the world should change their surname to Yuan, and they could not share the same surname as their father. Xuanzi changed to yuan, and Xuanxing changed to yuan. Second, the name of Kangxi in the Qing Dynasty was, so the surname "Xuan" was changed to "Yuan": it was explained in Kangxi Dictionary. At present, there are many people surnamed Xuan in Qian 'an City, Tangshan City, Hebei Province and Xia City, Tai 'an City, Shandong Province. (The characters in Gan 'an County, Tangshan City, Hebei Province are slightly different: single-sided+Xuan) There is a genealogical order: Guo Jishi is a freshman. In Gan 'an County, "wealth, beauty and happiness" are all "officials". As for the current Xuan surname, I don't know how it was handed down.
