成汉
Soon after taking over for Yu, the ambitious Huan turned his attention west, wanting to destroy Cheng Han, whose emperor Li Shi had mismanaged his state and lost the trust of his people. Most generals had concerns about the geographic barriers that isolated Cheng Han (which occupied modern Sichuan and Chongqing) from Jin, and that Later Zhao might make a surprise attack if it realized that Jin's forces were attacking Cheng Han. Late in 346, he launched the campaign. Li Shi sent his uncle Li Fu (李福), cousin Li Quan (李權), and Zan Jian (昝堅) to lead his forces to resist Huan, but Huan defeated Li Fu and then, abandoning most of his supplies and traveling light, quickly arrived in the vicinity of Cheng Han's capital Chengdu. Zan Jian's forces, in fear, collapsed, instead of being able to regroup to try to save Chengdu.
