What is the origin of Wu surname in Nanyang?

Nanyang Wu family is an important milestone in the development history of Wu family. Since the Eastern Han Dynasty, the descendants of Wu Han and his brothers have flourished, and several generations of descendants of Han Gong moved away from Nanyang with their father's official and went to Puyang, Juancheng, Chenliu, Changyuan, Runan Suiping, Gwangju Gushi and other places. And their descendants multiplied in the local area to form the Wu aristocratic family, which was called Puyang Wu, Chen Liuwu, Runan Wu and Gwangju Wu respectively.

During the Three Kingdoms period, Wei, Shu and Wu were three pillars. During this period, the descendants of Wu in Nanyang were more prosperous. In Wu Dong, Wu Dai's daughter, Wu Cheng's fifth grandson and the eldest son of Han Palace married Sun Jian, the secretariat of Yuzhou, as Sun Quan's mother. After Sun came to power, his mother, Mrs. Wu, was honored as the Queen of Wu Lie, and the Wu family became a relative of the country and was highly respected. In Shu, the daughter of Wu's fifth grandson married Liu Bei, and Liu Beili became the Queen of Mu. Amaran's brothers are surnamed Hou Baijiang, and his family is very rich in Sichuan. In Wei Dynasty, Sun Wu, the second son of Han, was loved by Cao Pi because of his literary talent. Both father and son were officials in the court. Wu's daughter married Sima Yi's son and Sima Yi's son respectively.

Since the late Three Kingdoms period, the Wu family living in the Central Plains began to move south to avoid war, and the Nanyang Wuhan Line gradually formed a situation of decline in the north and glory in the south. During the more than 300 years from the "An Shi Rebellion" in the late Tang Dynasty to Kublai Khan's destruction of Song Jianyuan, the Central Plains was broken, the people were poor, and Wu people migrated more frequently. A considerable number of Wu people left their homes and moved south to avoid chaos, entering Fujian and Guangdong along the coast, and some moved to Jiangxi, Sichuan and Hubei. By the end of Yuan Dynasty, due to long-term wars, floods and plagues, Nanyang was devastated, with barren land and few people. According to the records of Yuan history, in the first year of Qing Dynasty (A.D. 13 12), the total population of Nanyang Prefecture (including Ye County, Wuyang County and Biyang County at that time) was only 4,983, and the Wu clan was almost extinct. At present, there are five main sources of the Wu family living in Nanyang: one is the "Hongtong County immigrants" who moved from Shanxi in the early Ming Dynasty and Wanli years; Second, the hungry people who fled to Wan after the famine in Shanxi in the middle of Xuande in Ming Dynasty; Third, immigrants from Shanxi and other provinces moved to Nanyang in the late Ming and early Qing dynasties; Fourth, the descendants of the original Nanyang Wu who moved back to their hometown after the middle of Qing Dynasty; Fifth, because of work reasons, students transferred to other provinces and stayed in Nanyang.

The descendants of Nanyang Wuhan who moved south have survived for thousands of years. Now they are mostly distributed in Jiangnan, South China, Southeast and Southwest provinces and cities, and many of them have moved to Hongkong, Taiwan Province Province and overseas. They are the main branch of Wu surname in China, with the largest number of branches, the widest distribution and the largest population.
