《资治通鉴·唐纪·唐纪二十六》
太子拉他与自己同坐在一张榻上，流着眼泪对他说： 现在父皇的兄弟姊妹中，就只有一位太平公主了，如果把这些事禀告父皇的话，恐怕会让他老人家伤心，可如果不去禀告，又担心她所造成的危害会越来越严重，这可怎么办呢？ 
太子引与同榻坐，泣曰： 主上同气，唯有太平，言之恐伤主上之意，不言为患日深，为之奈何？ 
The Crown Prince pulled him to sit on a couch together and said to him with tears in his eyes: Now, there is only one Princess Taiping among his father's siblings. If these things are reported to his father, I'm afraid that he will be sad, but if he doesn't report them, he is worried that the harm she will cause will become more and more serious, so what can he do?
