The Kingdom of East Gok-Turks            

        Isbara lost the equilibrium under the hard conditions and he dismissed the commanders having high ranks whom he thought as being dependent to Ta-lo-pien. Consequently, some of those soldiers and princes obliged to want help from China. Işbara who brought fear and hatred around himself, understood regretfully that he lost lots from his strength, thus he personally asked the king of Sui for peace.

 

      Accepted the offer with pleasure and sent immediately envoys to him; C'ang Sun-şeng was the leader of the envoys. In the capital, this Chinese, in front of the lady and the other Turkish notables, insulted Işbara and he returned to his country after he announced the khan who recognized himself as being "the son of Emperor of China", as "Ç'en" (slave). The eastern kingdom was under the Chinese control. Isbara wrote in the year of 585 a letter to the emperor, "I will depend on you, pay taxes to you, give you precious horses as gifts. But, I won't change the language, I can't resemble our undulated hairs to yours, I can't order my people to wear the Chinese clothes, I can't obey the Chinese traditions. There is no way, because my people are very sensitive to those issues, they are like a hart that beats together. The Sui Emperor is the only sovereign in the world. There should not be two kings in the earth such as there are no two suns in the sky, etc."
