《新唐书·列传·卷六十四》
李泌入宫后，皇帝多次称赞舒王贤德，李泌揣摩到皇帝有废黜太子另立舒王之意，便说： 陛下只有一个儿子，还不相信他，却想立弟弟的儿子，臣不敢拿古代的事例来争辩。
泌入，帝数称舒王贤，泌揣帝有废立意，因曰： 陛下有一子而疑之，乃欲立弟之子，臣不敢以古事争。
After Li Mi entered the palace, the emperor spoke highly of King Shu's moral conduct on many occasions. Li Mi sensed that the emperor intended to depose the crown prince and make King Shu the heir, therefore he said: "Your Majesty has only one son, but you do not trust him; however, you want to choose the son of your younger brother as the heir. Your subject does not dare to argue by citing examples from ancient books."
