Wang Chengzong
In winter 820, by which point Emperor Xianzong had died and been succeeded by his son Emperor Muzong, Wang Chengzong died, although his subordinates kept the news of his death secret. With his sons Wang Zhigan and Wang Zhixin at Chang'an, the soldiers initially did not know whom to support as their new military governor. Wang Chengzong's staff member Cui Sui () issued an order in the name of Wang Chengzong's grandmother Lady of Liang (Wang Wujun's wife) naming Wang Chengyuan his successor. Wang Chengyuan accepted acting military governor authority but did not want to try to succeed Wang Chengzong permanently, and thus sent secret communications to Emperor Muzong offering to yield the circuit and then announced Wang Chengzong's death. Emperor Muzong, in response, named Tian the new military governor of Chengde and Wang Chengyuan the military governor of Yicheng Circuit (義成, headquartered in modern Anyang, Henan); Wang Chengyuan then left Chengde, ending the Wang family's hold on Chengde. Emperor Muzong gave Wang Chengzong posthumous honors.
