Historically, Yu was basically a typical southern surname. The earliest birthplace of the Yu family should be in Fengxiang to Xianyang, Shaanxi Province. Due to the lack of information, it is difficult to conduct detailed research. It is generally believed that Yu moved to Shexian County, Anhui Province in the Han Dynasty, where he settled, multiplied and developed. After the Han Dynasty, Yu surnames in the south and north of China were basically multiplying, while those in the north were much weaker. Many people surnamed Yu moved to Zhejiang, Jiangsu and Jiangxi. During the Wei, Jin, Southern and Northern Dynasties, the surname Yu had become a famous family in Xin 'an County. Due to the war in the north, it is inevitable that Yu moved to the south, and some of Yu's people moved to Hunan and Hubei. After the Tang Dynasty, the Yu family developed rapidly and formed two aristocratic families in the southeast. From the late Tang Dynasty and the early Song Dynasty, he moved to Fujian and Guangdong. During the Ming and Qing Dynasties, the Yu family not only spread all over the south of the Yangtze River, but also developed rapidly in all parts of the north.
