Ziying
Ziying ( *Tsə ′- ′eng, died January 206 BC) was the third and last emperor of the Qin dynasty. He ruled over a fragmented Qin Empire for 46 days from mid-October to early December in 207 BC.
Ziying was the only person within the Qin imperial court to defend and try to persuade Qin Er Shi against the wrongful executions of Meng Tian and Meng Yi. He lured Zhao Gao, the regent who assassinated Qin Er Shi, into a trap and killed him. Ziying later surrendered to Liu Bang, the leader of the first group of rebel forces to occupy Xianyang, the Qin capital. He was eventually killed along with his family by another rebel leader, Xiang Yu.
