The origin of the surname Han:
The surname Han comes from the surname Ji. The younger brother of King Zhou Cheng is the ancestor of Korea, and the territory is northeast of Hejin, Shanxi today. During the Spring and Autumn Period, his descendant Wu Zi, who had made outstanding contributions to the Jin Dynasty, was granted the title of Han Yuan. He took the name of the city as his surname and called him Han Wu Zi. Later generations began to have the surname Han.
His descendants held important positions in the Jin State and were very prominent. Later, they were divided into three parts of the Jin State with the two surnames Zhao and Wei, and were called the Seven Heroes. Their boundaries were in the southeast of present-day Shanxi and central Henan. Another source of the surname Han is that ethnic minorities changed their surname to Han.
