There is such a four-character couplet in the Universal Couplet of Bu's Ancestral Hall: "Looking at Pingyang from Buyi." As can be seen from this pair of couplets, one of the Bu surnames, perhaps the biggest origin, is a surname named after a feudal city. During the Spring and Autumn Period, Hu Shu, a doctor of the State of Jin, had three sons, named Rui and Yi respectively. Yishengyang, sealed in Buyi, is called "Buyang". Therefore, Yang's descendants take Yi as their surname, which is called Bu's. This couplet also points out the county name of Bu. Junwang is the general name of Junwang, which is an administrative division and a noble family. When county is used together, it refers to a famous family in a certain region and country. It is recorded in "Examination of Surnames" and "Hundreds of Surnames in Counties": "Giving looks at Pingyang." "Pingyang" here refers to Pingyang County, which was separated from Hedong County in the eighth year of Wei Zhengshi in the Three Kingdoms. Pingyang County (now southwest of Linfen County, Shanxi Province) was the location of the famous Bu family at that time.
After continuous migration, people now live in Jiangsu, Zhejiang, Hebei, Henan, Shandong, Liaoning, Hubei, Ningxia, Xinjiang, Jilin, Sichuan, Beijing and other places. Zhoukou also has a surname of step, but the number is very small. If not the teacher of Liu Yi Road Primary School, but Bu Zhonghai is the stationmaster of Zhoukou Evening News reporter station, then it will take a lot of trouble for reporters to get close to Bu's surname.
