《资治通鉴·唐纪·唐纪三十》
突骑施可汗苏禄素来生活廉洁勤俭，每次打仗所掠得的财物，都与各部落分享自己不留下私蓄，因此部众都乐于为他效命。
突骑施可汗功禄，素廉俭，每攻战所得，辄与诸部分之，不留私蓄，由是众乐为用。
Su Lu, the Khan of Tujue, has always lived a clean and frugal life. Every time he plundered wealth during wars, he would share it with each tribe, and kept nothing for himself. Therefore, the tribesmen were all willing to fight for him.
