《新唐书·列传·卷八十二》
使用他的力量，但不违背他的特长；让生活习俗一致，但不改变各人适合的习惯；引导他们向善，但不苛求他们做办不到的事；禁止他们的不良行为，但不布置他们做不想做的事。
用其力，不违其性；齐其俗，不易其宜；引其善，不责其所不能；禁其非，不处其所不欲。
Use his strength, but do not violate his specialty; let life customs be consistent, but don't change the habits suitable for each person; guide them towards good, but do not force them to do things they cannot do; prohibit their bad behaviors, but do not arrange for them to do things they do not want to do.
