Tang Daoxi (唐道襲) (died August 21, 913[1][2]) was an official and general of the Chinese Five Dynasties and Ten Kingdoms period state Former Shu.
In 913, with both he and Wang Yuanying suspecting the other of being ready to launch a mutiny, their forces engaged in a battle at the Former Shu capital Chengdu.
Wang Jian, along with several other regional warlords (Li Maozhen the military governor of Fengxiang Circuit (鳳翔, headquartered in modern Baoji, Shaanxi), Li Keyong the military governor of Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi), and Yang Wo the military governor of Huainan Circuit (淮南, headquartered in modern Yangzhou, Jiangsu)) refused to recognize the new Later Liang emperor, and Wang Jian and Yang issued a declaration urging the people to rise against Later Liang.
However, when they did not receive a positive response from other regional governors, Wang Jian decided to declare himself emperor of a new state of Former Shu.
As part of a series of personnel commissions after he declared himself emperor, Wang recalled Tang Daoxi from Lang Prefecture to serve as the director of palace communications (Shumishi).
Resentful of his removal, Wang Zongji was said to continue to foster his group of followers and consider a coup.
If Your Imperial Majesty believes that Zongyi's abilities are fit for him to serve as heir, you should create him crown prince as soon as possible.
The Crown Prince can attend to your meals in the morning and the evening, while your subject can command the soldiers to protect you.
Tang and Wang Zongyi made accusations against each other, and Wang Jian, not wanting to see this conflict growing larger, in 910 commissioned Tang the military governor of Shannan West Circuit (山南西道, headquartered in modern Hanzhong, Shaanxi) and gave him the honorary chancellor designation of Tong Zhongshu Menxia Pingzhangshi (同中書門下平章事).
Tang, in fear, made a report to Wang Jian stating that Zheng was intolerant and impatient, and should not be director of palace communications.
[1] In fall 913, Wang Jian planned a vacation away from Chengdu for the Qixi Festival[1] (on August 11 that year).
Meanwhile, Wang Yuanying's trusted officers Xu Yao (徐瑤) and Chang Qian (常謙) were gazing at Tang.
Further, he agreed to Tang's request to mobilize the regular troops to defend the palace (rather than the imperial guards, who were formally under Wang Yuanying's command).
[1] The next day (August 12), Xu, Chang, and Yan Lin (嚴璘), under Wang Yuanying's direction, attacked Tang's forces.
