《容斋随笔·卷十·杨彪陈群》
彰惇、蔡京主持政事，想要杀尽宋朝元祐时的忠良之臣，正义人士被禁银锢达三十年，因而导致了靖康年间的祸乱，士人不象华歆、陈群的几乎极少有了。
章惇、蔡京为政，欲殄灭元祐善类，正士禁锢者三十年，以致靖康之祸，其不为歆，群者几希矣。
Zhang Dun and Cai Jing were in charge of the government and wanted to kill all the loyal ministers during the Yuanyou era of the Song dynasty. The moral men were locked up in prison for thirty years, which led to the disasters during the Jingkang era. Unlike Hua Xin and Chen Qun, there were hardly any scholars left.
