《旧唐书·列传·卷一百三十六》
武则天知道是吉顼的首谋，便把他召来询问，吉顼说： 庐陵王及相王，都是陛下的儿子，先帝临终遗命托付给陛下，当自有主张，请陛下裁定。 
则天知顼首谋，召而问之。顼曰： 庐陵王及相王，皆陛下之子，先帝顾托于陛下，当有主意，唯陛下裁之。 
Wu Zetian knew that Ji Xu had been the mastermind, and therefore summoned him for questioning. Ji Xu said: “The Prince of Luling and the Prince of Xiang are both Your Majesty’s sons. The late emperor’s final instructions entrusted them to Your Majesty, and therefore it is up to Your Majesty to decide; Your Majesty should make the decision.”
