《宋史·列传·卷七十九》
唐介攻击宰相，皇上大怒，蔡襄急速进言说： 唐介实在是狂妄愚蠢，但念他出于进忠，希望保全宽恕。 不久贬唐介于春州，蔡襄又上疏认为这是必死的谪所，又得以改贬英州。
唐介击宰相，触盛怒，襄趋进曰： 介诚狂愚，然出于进忠，必望全贷。 既贬春州，又上疏以为此必死之谪，得改英州。
Tang Jie criticized the prime minister, and the emperor was furious. Cai Xiang quickly interceded: Tang Jie is really arrogant and stupid, but I believe that his intentions are loyal, and I hope he will be pardoned. Soon, Tang Jie was demoted to Chunzhou, and Cai Xiang memorialized that it was a place of certain death, and he was again demoted to Yingzhou.
