Zhang Cheng
In 229, when Sun Quan proclaimed himself emperor, Sun Shao was appointed General who Guards the North (). Sometime after 230, he was granted the nominal governorship of You Province. You Province comprised present-day Beijing, Tianjin, parts of northeast Hebei and western Liaoning. Far from Wu's northern frontier, the area never fell under their control; granting the title was merely a political statement of Sun Quan's assumed imperial power. In 234, during the fourth Battle of Hefei, Sun Shao and another general, Zhang Cheng, were tasked with leading a Wu army to attack Guangling and Huaiyin (). The episode ended in failure for Wu when Sun Quan's siege of Hefei was broken.
