Yu's surname did not enter the top 100 in Taiwan Province province. In ancient times, Yu was a transit warehouse for water transportation, and the official in charge of these warehouses in North Korea was called Dr. Zhang Yu. During the reign of Emperor Yao, some people inherited this official position, and later took the official name as the surname, which was called Yu. Yu is also an ancient surname, which has been scattered in various provinces and cities in China with the changes of the times. In ancient books, Cao Cao begged General Guan Yunchang to read the story of Yu Gong's pursuit of Zizhuo's obedient son in Spring and Autumn Annals to avoid being killed by Guan Yunchang. In Han Dynasty, Yu Pi and his son taught in the imperial court. Yu Sheng Kun Zhong was guarding Hengpu Pass in Tailing Town, Guangdong Province, and was renamed Dayuling because of his meritorious service. Yu Cheng, Yu Ben, Yu Dun, Yu Liang, Yu Yi, Yu Bing, Yu Wenjun and Yu Daolian are from Yanling, Yingchuan, Henan, and Yu Jianwu and Yu Xin are new savages in Nanyang, Henan. Yu Xin said in "Jiangnan Fu": "I inherited Yu Xin from the Zhou Dynasty, and I am an accomplished clan. I helped the Han dynasty through the country, and I was an official on the theory of Taoism. " This means that Yu's ancestors served as Liu's assistant in the Han Dynasty, played an important role in the founding of the country and governing the country, and participated in high-level state affairs. It can be seen that for more than 3,000 years, ancient celebrities have emerged in an endless stream, active in the political and cultural fields. Yu Liang, with military and political power, has made outstanding achievements. Yu Xin read widely and collected works of the Six Dynasties. Du Fu, a great poet in the Tang Dynasty, praised him for "Yu Xin's articles are older and his achievements are greater". At that time, the Yu family was regarded as a loyal and honest aristocratic family. Nowadays, in Xinye, Henan Province, there are the ancestral shrine of Hui Yu and the monument of Hu Shu to show their virtue. The Yu family has contributed to social development and left a glorious page in the big family of Chinese culture. Yu, the editor of Yu Family Records, wrote in the book that in the early years of the Eastern Jin Dynasty, the famous Yu family was ordered to go to Korea, which was the origin of blood and traceability that Yu, who was rooted in South Korea, wanted to admit. According to the Korean population statistics of 200 1,1,there are 97 surnames in China with a population of 16802. According to the national census of China in 20001year, there are about 50,000 people surnamed Yu, who are distributed all over the country. Many university professors, radio stations, newspapers, books and periodicals actually mistake the word "Yu" for Geng, Bo, Tang and Liao. China Xinhua Dictionary before 1972 interpreted the word "Yu" as "Dayuling", which is located at the junction of Guangdong and Jiangxi provinces. 1977 when I was studying in Shanxi university, I wrote to the editorial department of Beijing Xinhua dictionary and asked that it be annotated as "surname". Today, there are Yu ethnic groups in Guangxi, Hunan, Jiangxi, Gansu, Shanxi, Shaanxi, Jiangsu, Shanghai and Yunnan. According to the records of the Yu family in Guangdong, the ancestor of the Yu family in Guangdong was Geng Dongyun, an official in the Song Dynasty. During the Northern Song Dynasty, Yuan You came to Guangdong from Nanking, served as the envoy of Guangnan Road, and guided Yangcheng with his family. In the second year of Geng Guan, Song Zhenghe was promoted by Guangnan East Road. Because of the beautiful scenery in Dongguan, he lived in Dongguan Tea Garden (now Chashan Town) and named his place Yujiafang. In the 25th year of Hongwu in Ming Dynasty (1392), the 8th Sun Yu Dexin moved to Gu Yong (Chong) from Yujiafang, a tea garden, and then branched to Qishi Village in Chi Yong.
