Li Shi (Chinese: 李勢; died 361[1]), courtesy name Ziren (子仁), also known by his Jin dynasty-bestowed title Marquess of Guiyi (歸義侯), was the last emperor of the Di-led Cheng-Han dynasty of China.
Emperor Mu of Jin spared him and created him a marquess, a title he carried for the rest of his life.
In winter 346, the general Li Yi (李奕) rebelled and quickly advanced on Chengdu, but was killed by an arrow while sieging the city, and so his rebellion collapsed.
The state of Cheng-Han's affairs brought the attention of Jin's ambitious general Huan Wen.
In winter 346, Huan submitted a report requesting to attack Cheng-Han—and then, without approval from the imperial government, immediately departed.
However, Li Shi gathered the remaining troops and mounted a counterattack that was initially successful.
