What's the difference between "Yu" and "Yu" in surnames?

The difference between "Yu" and "Yu" in surnames: different origins, different migration and communication, and different ancestors.

First, the origins are different.

1, Yu: a typical surname of the Yellow Emperor's lineage spread from the Yellow River valley to the whole country. Yu originated from Ji's surname. In the early years of the Western Zhou Dynasty, Zhi Shu, the son of Ji's surname, was made a vassal state (Henan), and his descendants took Yu as their surname. ?

2. Yu: Ji's surname comes from Qin officials in the Eastern Zhou and Spring and Autumn Period. Because of the different pronunciations in ancient times, Yu characters have many different sources. According to research, Yu's birthplace is Fengxiang, Shaanxi.

Second, migration and communication are different.

1, Yu: The earliest spread and migration of the Yu family was in the north of Qinyang, Jiaozuo, which is the seat of the ancient kingdom and the birthplace of the Yu family. After the demise of Zhi State, the Yu people mainly lived in present-day Henan, and also mainly lived in Henan, such as Fangcheng, Wu Tang, Xuchang, Funiu Mountain and other places.

2. Yu: Yu's earliest birthplace should be in Fengxiang to Xianyang, Shaanxi. During the Spring and Autumn Period, Qin took Yong (now southeast of Fengxiang, Shaanxi) as the base area, occupying the central part of Shaanxi and the southeast end of Gansu. The descendants of Yu should have multiplied in this area in the Spring and Autumn Period.

Third, the ancestors are different.

1, Yu: branch secretary.

2. Yu: Ji Youyu.
