Chencang is a siege fought by the Kingdom of Shu during the Second Northern Expedition of Zhuge Liang. The Wei forces outwitted Zhuge Liang by building inner walls so that when the battered Shu forces finally breached the outer wall, they would face new defenses with fresh troops. Upon hearing of Zhang He's arrival, Zhuge Liang withdrew with his army losing valuable officers in the battle. Wei commander Hao Zhao won fame for this victory, but died afterwards at Chang'an. In Romance of the Three Kingdoms, it was during the course of this battle that Shu lost Zhang Bao and the death of Wei's general Wang Shuang.
