The Short Weakness Period After Tardu (603-619)            

         
       After the disappearance of Tardu, the number of the rebellious increased in the country, and the order spoiled. The grandchild of Tardu, who tried to cooperate with Suis against the Khan Şi-pi, who had been the new power in the Eastern Khanate, had left his country and preferred to live in the Palace of China, from where he had been taken over and killed (619) by Şi-pi. The things began to improve during the period of Şi-koen, one of the relatives of Tardu, who was announced as being the khan by the Parliament.
