《宋史·列传·卷九十六》
李定逃避居丧守孝，于是不认母亲，破坏人伦，逆忤天理，而朝廷打算以他为御史，御史台因为他罢去陈荐，舍人院因为他罢去宋敏求、吕大临、苏颂，谏院因为他罢去胡宗愈。
李定避持服，遂不认母，坏人伦，逆天理，而欲以为御史，御史台为之罢陈荐，舍人院为之罢宋敏求、吕大临、苏颂，谏院为之罢胡宗愈。
Li Ding evaded mourning for his parents, so he disowned his mother, destroyed human relationships, and violated the principles of nature. However, the imperial court planned to appoint him as an imperial censor. The Censorate removed Chen Jian on his account, and the She Ren Yuan removed Song Minqiu, Lv Dalin, and Su Song on his account. The Institute of Remonstrance removed Hu Zongyu on his account.
