Huan Wen
Huan Wen was a rising general in the early 340s and served as Yu Yi's Subcommander during the expedition on 343. With the support of the minister, He Chong, he took over command of the western provinces following the death of Yi in 345. In 347, Huan Wen campaigned against the western Ba-Di state of Cheng Han and conquered it in 348. Huan Wen's victory unified southern China, and because of that, he became extremely popular among the common people. The court began to fear Huan Wen's power and status as a national hero, so they introduced a talented man named Yin Hao to serve as his rival and maintain a balance of power.
