陳平
In 209 BC, during the reign of Qin Er Shi, rebellions erupted throughout China to overthrow the Qin dynasty. Chen Ping pledged his service to Xiang Yu, a prominent rebel leader. After the fall of the Qin dynasty in late 207 BC, Xiang Yu marched his army into the Qin capital Xianyang and plundered and pillaged the city. Around this time, Chen Ping defected from Xiang Yu's side to Liu Bang, another prominent rebel leader. Liu Bang appointed Chen Ping as "Lieutenant Who Protects the Nation" ().
