Migration and Distribution (Lack of information) The Kuai surname is not included among the top 100 surnames in the Chinese mainland and Taiwan. In the Shang Dynasty, there was a vassal state called Kuai (present - day Kuai Township west of Luoyang City, Henan Province). Most of the people living in this state took the name of the state as their surname and were called the Kuai clan. During the Spring and Autumn Period, an official of the Jin State named De was enfeoffed in Kuai (the same place as above). His descendants took the name of the fiefdom as their surname and were also called the Kuai clan. So far, it has a history of more than 2000 years. Similarly, the Duke Zhuang of the Wei State was named Kuai Kui, and his descendants took one character from his name as their surname, also called the Kuai clan. In the Han Dynasty, a place named Kuai Township appeared in Henan (on the east bank of the Jianshui River in the western suburbs of present - day Luoyang City, Henan Province). The local residents at that time all took Kuai as their surname. The Kuai surname is mainly distributed in the area around Xiangyang, Hubei Province.
