《史记·七十列传·滑稽列传》
所以说，酒喝得过多就容易出乱子，欢乐到极点就会发生悲痛之事。所有的事情都是如此。 这番话是说，无论什么事情不可走向极端，到了极端就会衰败。
故曰酒极则乱，乐极则悲；万事尽然，言不可极，极之而衰。 
Therefore, it is said that drinking too much alcohol is prone to causing chaos, and extreme joy will lead to sorrow. This is true for all things. This saying means that no matter what, one should not go too far, because going to extremes will lead to decline.
