《礼记·礼运》
这时候尽管用严刑峻罚来挽救，但因风俗凋弊，由此而引起法令无常，法令无常自然又引发礼仪乱套，礼仪乱套就让士人无法做事。
刑肃而俗敝，则法无常；法无常，而礼无列；礼无列，则士不事也。
At this time, although severe penalties are used to save, due to the decline of customs, the laws become impermanent, and the impermanent laws naturally lead to chaos in etiquette, and the chaos in etiquette makes it impossible for the literati to do things.
