 It was said that Tian Xu was violent and often committed crimes, but Tian Yue did not have the heart to give him heavy punishment, although on one occasion he whipped Tian Xu and briefly detained him, drawing resentment from Tian Xu.Tian Xu also resented Tian Yue because Tian Yue, frugal by nature, restricted his family members' monetary expenditures, such that Tian Xu felt that the expenditures were insufficient for him.In 781, Tian Yue, along with several other military governors, rose in rebellion against Emperor Daizong's son and successor Emperor Dezong, but by 784, Emperor Dezong, who was then in desperate straits due to the rebellion at the capital Chang'an by Zhu Ci, issued a general pardon.
