Mandarin form of the surname 劉, referring to a ‘type of axe used as a weapon’ or meaning ‘kill’ in ancient Chinese: (i) from Liu (劉), the name of an ancient state (located in Tang County in Hebei province). After this state was annexed during the reign of King Xuan of Zhou (reigned 827–782 BC ), some people from it adopted 劉 as their surname. Liu Bang (劉邦) (256–195 BC ), the founder of the Western Han dynasty (202 BC - 25 AD ), is said to have been a descendant of one of these people. (ii) from the names of two other Western Han nobles, Lou Jing and Xiang Bochan, who were given the surname Liu (劉) by Liu Bang (Emperor Gaozu of Han, 256–195 BC ). In addition, one of Liu Bang's daughters was said to be sent to marry Modu Chanyu (died 174 BC ), the then chief of the Huns, after the campaign at Baideng in 200 BC , and some of their descendants later inherited Liu (劉) as their surname.
