Li Su

Li Su (died 192) was a military general serving under the warlord Dong Zhuo during the late Han Dynasty era of Chinese history.

Li Su originally served as a Commandant of Cavalry (騎都尉) under Dong Zhuo. He later assisted Lü Bu, who was from the same village as he, in the assassination of Dong Zhuo. Li Su's role was to pretend to guard the entrance and to attack Dong Zhuo upon his entry. Dong Zhuo called out for the assistance of Lü Bu, who was his adoptive son, and was promptly slain by the latter.

Following Dong Zhuo's death, Li Su served under Lü Bu as he contested with Dong Zhuo's followers for control. Following his return from a defeat against Niu Fu, Li Su was executed by Lü Bu.

In Luo Guanzhong's historical novel Romance of the Three Kingdoms, Li Su was also credited with persuading Lü Bu to kill his adoptive father Ding Yuan and join Dong Zhuo. Amongst the many gifts that Li Su took along with him was the Red Hare.
