(1) Manchu surname in Qing Dynasty, from Shenyang, Liaoyang and other places, later changed to Yu surname, Manchu Eight Banners surname Ni Maha. Today, Yi, Tujia, Hui, Korean and other ethnic groups all have surnames. Ancestor: Yu Yu. The legendary ancestor of Xinglin in China. He once tasted the herbs of Shennong and was familiar with the characteristics of various herbs. He knows how to use the modern surgical technique of "peeling, removing tendons and washing the five internal organs" and is respected as an imperial doctor. On one occasion, Yu Yang, the youngest son of the Yellow Emperor, was terminally ill. The Yellow Emperor asked him to go for treatment, but when he arrived, Yu Yang was very angry. The Yellow Emperor loved this son so much that he couldn't help feeling sad. He immediately cut open Yuyang's stomach, cleaned his internal organs and brought him back to life. Someone asked him afterwards, "If you cut open a dying man's stomach, don't you have to bear the blame if you can't save him?" He said: "The first condition of being a doctor is to forget yourself. Only by forgetting yourself can you put your heart on the patient. " Because of his superb medical skills, no matter how serious his illness is, he can be recovered, so people call him Yue, which is homophonic with Yu Yu, and later called Yu. Later, he complied with public opinion, taking danger as his surname and thinking of his ancestors.

Yu's surname has existed for a long time, dating back to the era of the Yellow Emperor 5,000 years ago. Later, in the Spring and Autumn Period, both Zheng and Chu joined the ranks of Yu. Even so, there are very few people with the surname Yu handed down in history before Sui and Tang Dynasties. Only a few people: Yu Boya, a Chu state in the Spring and Autumn Period and the Warring States Period; Yu Lin was originally the king of Khotan (now Xinjiang Autonomous Region) in the Eastern Han Dynasty, and later Li Guiwang; Yu Zong was born in Xuancheng (now Anhui) in the Eastern Jin Dynasty; Yu Shu was born in the Southern Song Dynasty (now Nanjing). Although the number is small, it is enough to show that before the Sui and Tang Dynasties, there were people surnamed Yu in Hubei, and some people surnamed Yu crossed the Yangtze River and entered Jiangdong (as for them, they may be ancient ethnic minorities. Save it for reference). When Wu Zetian was in the Tang Dynasty, Yu Wenjun, a native of Jiangling, Jingzhou (now Qianjiang City, Hubei Province), dared to say that there was an extra mountain in Xinfeng for no reason, because Wu Zetian "lived in the Yang position". This statement angered Wu Zetian and exiled him to Lingnan, which was very remote at that time. In this way, the descendants of Yu came to Guangdong and Guangxi in the south of China. Therefore, there should be many Yu surnames in southern China who are descendants of this Yu Wenjun. According to the records of Hundred Surnames in Counties and Counties and Textual Research on Surnames, Yu has four surnames, namely Hedong County, Hanoi County, Hejian County and Jiangling County. These data show that Yu lived in Shanxi, Henan, Hebei, Hubei and other provinces for a long time during or before the Sui and Tang Dynasties, with a prosperous population. After entering the Song Dynasty, Yu suddenly shone brilliantly. In the Song Dynasty alone, 44 people were included in the Dictionary of Names of Past Dynasties in China. Except for three people who have no native place, the rest are Zhejiang, Anhui, Fujian, Jiangsu, Jiangxi and other places, and Yu's name is distributed in the above places. In the early Ming Dynasty, Yu was moved to Shaanxi, Gansu, Hebei, Tianjin and other places as one of the surnames of the locust tree people who moved to Hongdong in the Ming Dynasty. During the Ming and Qing Dynasties, Yu was still in East China, but there were more and more scattered places. Today, the Yu family is widely distributed in China, especially in Anhui, Zhejiang, Jiangsu and other provinces. The surnames of Yu in these three provinces account for about 70% of the Han population in China. Therefore, China's first surname 1 17 has a large population, accounting for 0. 12% of the Han population in China.
