《汉书·传·王贡两龚鲍传》
昌邑王刘贺虽然不守正道，但是还知道敬重礼遇王吉，因此他下令说： 我的修养品行不可能没有懈怠之处，中尉王吉忠心耿耿，多次指正我的过失。
王贺虽不遵道，然犹知敬礼吉，乃下令曰： 寡人造行不能无惰，中尉甚忠，数辅吾过。
Although Liu He, the King of Changyi, did not abide by the right path, he still knew how to respect and treat Wang Ji with courtesy. Therefore, he ordered: My conduct and character cannot be without shortcomings. Wang Ji, the Lieutenant, is loyal and devoted, and has repeatedly pointed out my mistakes.
