《旧唐书·本纪·卷二十》
刘季述便拿出百官们一起签名的文书，说： 皇上倦于治理国事，朝廷内外官员们的情绪都希望由太子监国处理国政，请陛下在东宫颐养天年。 
季述即出百官合同状，曰： 陛下倦临宝位，中外群情，愿太子监国，请陛下颐养于东宫。 
Liu Jishu then produced the document that had been signed by all the officials and said: The emperor is tired of governing the country. The officials inside and outside the court hope that the crown prince will be regent and handle the affairs of state. Please, Your Majesty, retire to the East Palace and live out your years in peace.
