The surname Kuài is a Chinese surname and one of the surnames of ethnic minorities. According to the records in "Hundred Family Surnames", the surname Xi is the name of a tribe derived from the Mao tribe (xūn zú), a minority group in ancient China. It is said that this ethnic group first lived in today's Shaanxi Province, and later migrated to Henan, Anhui and other regions. The population with the surname Xi is relatively small, and it is relatively low in the national ranking of surnames.
In ancient times, the Mao people were an ethnic minority distributed in the Central Plains and South China. Their living and cultural habits were different from other ethnic minorities such as the Han people. Although the Mao people have a small population, they have had a certain influence in history. For example, during the Zhou Dynasty, the Mao tribe was one of the military supporters of the Western Zhou royal family and had a certain degree of power in the Central Plains.
