Emperor Yang agreed and subsequently, Sheguy attacked khagan, defeating him and forcing him to flee to Gaochang.
Emperor Yang, pleased with this development, awarded Pei with a sable coat and jewels that Daman offered as tribute.
In 611, he was created Heshana Khagan (曷薩那可汗) by imperial decree and was married to a Chinese princess.
