Западная Янь
Yao Chang initially opted to keep his troops mobile, as he anticipated Murong Hong's Western Yan forces to siege Chang'an and destroy Former Qin and then depart for their homeland, so that he could take Chang'an without major engagements. In doing this, he hoped to conserve and increase his strength while his rivals battled. He therefore temporarily placed his capital at Beidi (北地, in modern Tongchuan, Shaanxi), seizing the cities of the modern northern Shaanxi. Despite this, he had periodic battles with Former Qin and Western Yan forces, as Former Qin and Western Yan also battled each other.
