Tian Yue
In 779, Tian Chengsi died. At the recommendation of Li Baochen, Emperor Daizong allowed Tian Yue to inherit his post — initially as acting military governor, and then officially as military governor. Contrary to Tian Chengsi's defiant stance against the imperial government, Tian Yue was initially, on the surface, respectful and submissive, although he continued to rule his realm in a "de facto" independent manner. This continued after Emperor Daizong died later in 779 and was succeeded by his son Emperor Dezong, who took a harder line against military governors who had ambitions to rule independently. In 780, for example, when Emperor Dezong sent 11 officials as surveyors of the Tang realm, one of the surveyors Hong Jingguan () was responsible for surveying the Hebei region (河北, i.e., roughly modern Hebei, Beijing, and Tianjin). When Hong visited Weibo and heard that Weibo had 70,000 troops, he issued an order that Weibo reduce its army by 40,000. Tian Yue pretended to follow his orders and also issued an order cutting 40,000 soldiers from his army and sending them to farm. He then summoned those soldiers to be cut and stated to them, "You have long been in the army, and you all have parents, wives, and children. Now, if the surveyor forces you to leave the army, how are you going to feed your families?" Tian then spent his own wealth to pay for these soldiers and kept the 40,000 in the army. It was said that thereafter, the army were grateful to Tian and resentful of the imperial government. Nevertheless, pursuant to the customs of Emperor Daizong's time, when Emperor Dezong celebrated his birthday in summer 780, both Tian and Li Zhengji offered a large amount of silk to Emperor Dezong as a birthday gift. Emperor Dezong, instead of receiving them into the palace storage as his father would have, had the silk turned over to the imperial treasury for state use and announced that those were used to satisfy Weibo's and Pinglu's taxes — implicitly informing Tian and Li Zhengji that he was dissatisfied that Weibo and Pinglu were not paying taxes.
