刘武周
Meanwhile, with his generals Zhang Ju () and Liu Min () having defected to Tang and with Liu Wuzhou having been defeated by Tang earlier in 620, Liang was fearful that he would become next, and he sent his official Lu Jilan () to point out to Ashina Qilifu that he should act against Tang before it became too strong to control. Ashina Qilifu agreed, and made a grand plan to attack Tang on several sides, incorporating Xi tribe forces and those of another rebel ruler, Dou Jiande the Prince of Xia, into the plan. However, before Ashina Qilifu could launch his plan, Ashina Qilifu died. He was succeeded by Ashina Duobi (as Jiali Khan).
