《汉书·传·楚元王传》
逐渐衰落一直到了暴秦，烧经书，杀儒士，制定禁书法律，赞扬古代的被治罪，大道法术从此灭绝。
陵夷至于暴秦，燔经书，杀儒士，设挟书之法，行是古之罪，道术由是遂灭。
The decline gradually continued until the violent Qin Dynasty, burning books, killing Confucian scholars, formulating laws to ban books, praising the ancient ones being punished, and the Great Way and the laws and methods thus perished.
