)[1] During the subsequent reign of Li Cunxu's adoptive brother and successor Li Siyuan, An Congjin successively served as the military governor (Jiedushi) of Baoyi (保義, headquartered in modern Sanmenxia, Henan) and Zhangwu (彰武, headquartered in modern Yan'an, Shaanxi) Circuits, but it was said that during those terms he did not conduct any campaigns.
[2] An Congjin was recalled to the capital Luoyang to serve as the commander of the cavalry guards, and also given the title of military governor of Shunhua Circuit (順化, headquartered in modern Huai'an, Jiangsu).
)[1] Li Conghou's court scene was dominated by his chiefs of staff (Shumishi) Zhu Hongzhao and Feng Yun.
[2] In early 934, they tried to dislodge Shi and Li Congke by issuing orders transferring Li Congke from Fengxiang to Hedong, Shi from Hedong to Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei), and Fan Yanguang from Chengde to Tianxiong Circuit (天雄, headquartered in modern Handan, Hebei).
)[3] Subsequently, in the middle of Li Congke's Qingtai era (934-937), An was commissioned the military governor of Shannan East Circuit (山南東道, headquartered in modern Xiangyang, Hubei).
[1] In 936, Shi Jingtang, with aid from Khitan's Emperor Taizong, rebelled against Li Congke, and after the Later Tang forces were defeated by joint forces of Khitan and Shi's newly established Later Jin, Li Congke committed suicide, ending Later Tang and allowing Later Jin to take over its territory.
[4] Shi allowed An Congjin to remain at Shannan East, and bestowed on him the honorary chancellor designation Tong Zhongshu Menxia Pingzhangshi (同中書門下平章事).
He often intercepted the tributes sent by Later Jin's vassal state Chu; he also received many desperate people to increase the number of his troops.
He sent a messenger to Shannan East to inquire of An, "We are leaving the post at Qing Prefecture [(青州, Pinglu's capital)] open for you, sir.
Meng declined to support him, on account of the distance between Shannan East and Later Shu proper, while Gao tried to dissuade him from a rebellion.
Gao, at the suggestion of his general Wang Baoyi (王保義), reported the contents of An's communications with him to Shi, and offered to support the Later Jin imperial government in any action against An.
[6] An Congjin, unaware of this development, launched his rebellion shortly after, and he first attacked neighboring Weisheng Circuit (威勝, headquartered in modern Nanyang, Henan).
He also sent his brother An Conggui (安從貴) to attack Cai Xingyu (蔡行遇) the prefect of Jun Prefecture (均州, in modern Shiyan, Hubei).
Gao's officers Wang Qing (王清) and Liu Ci (劉詞) then led the soldiers in scaling the walls, causing the city to fall.
