Also in 611, angry that Western Tujue's khan Ashina Daman, while nominally submissive, had refused to visit him, Emperor Yang had Pei Ju persuade Ashina Daman's subordinate khan Ashina Shegui () to rebel against Ashina Daman, promising to give him a Sui princess in marriage. Ashina Shegui thus rebelled against Ashina Daman, forcing Ashina Daman to flee, first to Gaochang, then to Sui. Emperor Yang accepted Ashina Daman's submission, and thereafter divided his people into three groups, while leaving Ashina Daman as titularly khan, although he never allowed Ashina Daman to return to his people.
