Official surnames are widely distributed in China, especially in Shandong, Fujian, Jiangxi, Guangdong, Hunan and Sichuan provinces. The official population ranks 274th in China. The specific surname of an official is unknown, but there should be no doubt that his surname is North. This surname, born in the north, flourished in the south in later generations. Because the official surname has been very quiet since its birth, this situation continued until the Song and Yuan Dynasties, so it is difficult to know the details of the early reproduction of the official surname.
Distribution of official surnames:
The official surname is the 274th surname in modern times, with a large population, accounting for about 0.02% of the Han population in China. In addition, it is said that "Guan was a Cai native of Pingdu Prefecture in the Song Dynasty, and he was a big family of states and counties", indicating that there was also a big family of officials in Pingdu Prefecture in the Song Dynasty (now Pingdu, Shandong Province). During the Song and Yuan Dynasties, northern provinces such as Henan, Shanxi, Shandong and Shaanxi all had official surnames.
In southern provinces such as Sichuan, Zhejiang, Jiangsu, Anhui, Fujian, Hubei, Hunan and Guangdong, official surnames have been widely distributed and have a large population. At the end of the Tang Dynasty, eunuchs lived in Dongyang, because in the post-Tang Yizong period, the Tao of the Tang Dynasty gradually declined, and Huang Chao spread chaos. Grandmother Zhu Wei moved to Shibi Village, Ninghua County, Tingzhou Prefecture, Fujian Province to avoid disasters. In the early Ming Dynasty, the official surname of Shanxi was moved to Shandong, Hebei, Henan, Shaanxi, Beijing and other places as one of the surnames of people who moved to Hong Tong.
