《明史·列传·卷一百九十五》
江彬知道钱宁容不下自己，左右又都是钱宁的党羽，便想凭借边防兵来巩固自己的地位。他于是向皇帝称赞边军远比京军骁勇强悍，请求互相调换进行操练。
彬知宁不相容，顾左右皆宁党，欲籍边兵自固，固盛称边军骁悍胜京军，请互调操练。
When Jiang Bin realized that Qian Ning could not tolerate him, and his subordinates were all Qian Ning's followers, he wanted to consolidate his position based on the border defense troops. So he praised the border troops to the emperor, saying that they were much more brave and formidable than the imperial troops, and requested to have them rotate and train with each other.
