田承嗣
By 775, when Emperor Xuanzong's grandson Emperor Daizong waged a campaign to remove Tian Chengsi, indeed, Tian Yue, as Tian Chengsi's chief assistant, was named in Emperor Daizong's edict as the only other person than Tian Chengsi who would not be allowed to keep his posts — as Emperor Daizong stated that even the other Tian clan members, if they abandoned Tian Chengsi, would be allowed to do so. During the campaign, however, as part of Weibo's initial losses, Tian Yue suffered a defeat by several generals attacking Weibo from the south — Li Zhengji the military governor of Pinglu Circuit and Li Zhongchen the military governor of Huaixi Circuit (淮西, headquartered in modern Zhumadian, Henan) — at Chenliu (陳留, in modern Kaifeng, Henan). Subsequently, though, Tian Chengsi was able to exploit the ambitions of Li Zhengji and Li Baochen — themselves military governors who ruled their realms in "de facto" independent — to lead to the collapse of the imperial coalition, causing Emperor Daizong to abandon the campaign.
