《文心雕龙·铭箴》
汉末潘勖的《符节箴》，比较简要，却失于肤浅；东晋温峤的《侍臣箴》，内容广博，却过于繁杂；西晋王济的《国子箴》，虽然旁征博引，内容却很贫乏；潘尼的《乘舆箴》，内容正确，但又写得过于芜杂：所有这些相继出现的作品，很少写得恰到好处。
至于潘勖《符节》，要而失浅；温峤《侍臣》，博而患繁；王济《国子》，文多而事寡；潘尼《乘舆》，义正而体芜：凡斯继作，鲜有克衷。
Fan Xu's Warning Admonishment in the Late Han Dynasty was relatively brief, but it was superficially written. Wen Qiao's Official Admonishment in the Eastern Jin Dynasty had extensive contents but was written too complicatedly. Wang Ji's Scholars' Admonishment in the Western Jin Dynasty cited extensive examples, but the contents were poor. Pang Ni's Imperial Admonishment had correct contents but was written too widely. All these works were written one after another, and few of them were written just right.
