後秦
Also in 409, Qifu Gangui escaped and returned to Wanchuan to join his son Qifu Chipan. He soon redeclared independence and reestablished Western Qin as its king. He soon launched several campaigns against Later Qin and inflicted substantial damage, although he would apologize in 411 and again declared himself a Later Qin vassal. Later that year, however, he resumed his attacks.
