《宋史·列传·卷四十四》

乃上言曰： 太祖初有天下，监唐末五代方镇武臣、土兵牙校之盛，尽收其威权，当时以为万世之利。及太宗时，将帅率多旧人，犹能仗威灵，禀成算，出师御寇，所向有功。
So he said: Taizu began to have the world, in view of the strength of the warlords and the local soldiers during the late Tang Dynasty and the Five Dynasties, and he took all their prestige and power. At that time, it was believed to be the benefit of all generations. When it came to Taizong, most of the generals were old people, and they could still rely on mighty power and follow the established plan to lead troops to fight the enemy. They were successful everywhere they went.
