《元史·列传·卷九十一》
时侍御史李国凤亦上书皇太子说： 不花骄傲专横，揽权纳贿。趋炎附势之徒，无不出其门下，颇有点像赵高、张让、田令孜的样子，实不能任其继续发展。不花的罪恶，众人共知，唯皇上与殿下还不了解。
会侍御史李国凤亦上书皇太子，言： 不花骄恣无上，招权纳赂，奔竞之徒，皆出其门，骎骎有赵高、张让、田令孜之风，渐不可长，众人所共知之，独主上与殿下未之知耳。
At that time, Shi Yushi and Li Guofeng also wrote to the crown prince, saying: Buhua was arrogant and domineering, and he accepted bribes. The people who follow the powerful to seek personal gain all came out of his school, quite like Zhao Gao, Zhang Rang, and Tian Lingzi. They really cannot be allowed to continue to develop. Buhua's crimes are known to all, but only the emperor and the prince do not know.
