《资治通鉴·唐纪·唐纪十三》
突厥本是贫弱的民族，我大唐接收并养护他们，估计他们感恩戴德的想法刻骨铭心、深入骨髓，怎么肯成为祸患呢？
突厥贫弱，吾收而养之，计其感恩，入于骨髓，岂肯为患！
The Turks were originally a poor and weak nation. My Great Tang has accepted and taken care of them. It is estimated that they are so grateful to me that it has penetrated into their bones. How could they be willing to become a disaster?
