慕容沖
Western Yan forces, under its now-emperor Murong Chong, occupied Chang'an, and Western Yan and Later Qin battled on-and-off. However, the Western Yan people were unhappy that Murong Chong was not leading them back to their homeland in the east, and, in 386, Murong Chong was assassinated in a coup and replaced with Duan Sui, who was then assassinated and replaced with Murong Yi, under whom the Western Yan people abandoned Chang'an and headed east. Briefly, Chang'an was held by the Xiongnu chief Hao Nu (郝奴), but Yao Chang then advanced on Chang'an, and Hao surrendered. Yao Chang made Chang'an his capital and claimed the title of emperor. He created his wife Lady She as empress and his son Yao Xing as crown prince.
