Wang Ping, courtesy name Zijun, was a military general of the state of Shu Han in the Three Kingdoms period of China. Originally a military officer serving under the warlord Cao Cao. In 219, he defected to Cao Cao's rival Liu Bei during the Hanzhong Campaign. Although he was a talented orator, Wang Ping never learned to read because he joined the army at a young age. However, he did not let this disadvantage stop him and had his clerk help him with his reports. Known for his self discipline, he steadily rose through the ranks to become a senior general. During his career, he defeated Zhang He, quelled Wei Yan's alleged rebellion and was the leading commander of the Shu forces during the Battle of Xingshi. The highest position he reached was Senior General Who Guards the North (鎮北大將軍).

Wei Yan, courtesy name Wenchang, was a Chinese military general and politician of the state of Shu Han during the Three Kingdoms period of China. Originally a subordinate of the warlord Liu Bei in the late Eastern Han dynasty, Wei Yan rose through the ranks and became a general when Liu Bei seized control of Yi Province in 214. His performance in battle helped him to become a prominent figure in the Shu military in a short period of time. He was later appointed as the Administrator of Hanzhong Commandery and as an Area Commander in 219. Between 228 and 234, he participated actively in the Northern Expeditions led by the Shu regent Zhuge Liang against Shu's rival state, Cao Wei. After Zhuge Liang's death in c.September 234, Wei Yan was killed by another Shu general, Ma Dai, for alleged treason.
