The continuing military pressure of the Qing forced Youlang to withdraw further into the south and west, first to Guilin in Guangxi, then to Jiangxi and Hunan, then south again to Nanning in Guangxi. He had a number of experienced and devoted followers, but became increasingly reliant on the military support of local warlords and bandit chieftains. The best and most effective of these was Li Dingguo, who for five years was highly successful in enlarging Southern Ming territories in the southwest. This success, however, caused the Qing to place the entire region in the hands of the extremely capable Hong Chengchou, who was named governor-general of five provinces. By 1658 Youlang had been forced back into Yunnan, on the very edge of China's southwestern frontier.
