How many people are surnamed Yang in China?

There are four main sources of Yang's surname:

1, from Ji's surname. In the Tang Dynasty, Zhou Chengwang named his brother Yu Shu. After his son Xie succeeded to the throne, he was renamed Jin Hou because there was water in the southern Tang Dynasty. During the Spring and Autumn Period, Yang perished in the State of Jin and became the fief of the sheep tongue in the State of Jin. Emperor Wu of Jin (the grandson of Xie 10) named his second son Boqiao Yang Hou, the ancestor of Yang. Boqiao's grandson suddenly went to eat at the sheep's tongue, became a doctor at the sheep's tongue, and was a family of sheep's tongues. The grandson of Tu, whose name is Uncle Xiang, was awarded the title of Yang Shiyi (present-day Hongdong, Shanxi) because of Dai Jin's meritorious service, and his son took the city as his surname Yang. In 5 14 BC, Jin wiped out the Qi and Qiang ethnic groups, and the wanderer fled to Huashan Xiangu, and later lived in Huayin (now Shaanxi), known as Yang in history and Yang Zhengzheng in history. It's for Shanxi poplar.

2, from the surname. During the Three Kingdoms period, Zhuge Liangping gave local ethnic minorities surnames Zhao, Zhang, Yang and Li after mourning for foreigners (a branch of Hunan, Guizhou and Liao countries).

3. From his surname to Yang. For example, after Fujian Lin moved to Meizhou, Guangdong, he changed his surname to Yang. According to Northern History, the real name was Wei Chi, and later it was changed to Yang et al.

His family changed his surname to Yang. For example, after Emperor Xiaowen of the Northern Wei Dynasty moved the capital to Luoyang, his three-character surname was changed to Yang.

It can be seen that it has a history of more than 2400 years from the earliest to now.
