사조의
Shi Siming was himself assassinated by his son Shi Chaoyi in 761, and Shi Chaoyi took the throne. After a Tang and Huige joint force again recaptured Luoyang in fall 762, Tian withdrew his force and joined Shi Chaoyi at Wei Prefecture (衛州, roughly modern Puyang, Henan) to fight against the Tang forces commanded by Pugu Huai'en, but Pugu defeated them, forcing them to further flee north. Yan generals began to desert Shi Chaoyi en masse, but for some time, Tian did not, and by the time around new year 762, he was under siege in Mo Prefecture (莫州, in modern Cangzhou, Hebei) with Shi Chaoyi. He proposed to Shi Chaoyi that Shi Chaoyi head to You Prefecture (幽州, i.e., the headquarters of Fanyang Circuit) to seek reinforcements, and that he would stay and defend Mo Prefecture. Shi Chaoyi agreed, but as soon as Shi Chaoyi left Mo Prefecture, Tian turned against him and surrendered Mo Prefecture to Tang, presenting Shi Chaoyi's empress dowager, empress, and children to Tang. Shi Chaoyi, finding the situation hopeless, committed suicide in flight.
