Guan Xing (?-234) was a Shu general and Guan Yu's second son, a younger brother of Guan Ping, and older brother of Guan Yinping and Guan Suo. When Liu Bei raised his army for the fight against Wu, he participated so that he could avenge his father. He made a pact of brotherhood with Zhang Fei's son, Zhang Bao, and the two proved to be a formidable force during the battles in the North. When Zhang Bao died in 229 AD at the Battle of Chencang, he left everything to Guan Xing and Xingcai, and Guan Xing fell ill and died after the Battle of Wuzhang Plains.
