《旧唐书·列传·卷三十二》
当时朝廷又诏令尚书省五品以上重新评议，礼部尚书杨思敬建议说： 按照谥法 已经有过失能够改叫作恭，请定谥为恭。 
时有诏令尚书省五品已上重议，礼部尚书袁思敬议称： 按谥法 既过能改曰恭 ，请谥曰 恭 。 
The Court then ordered the Ministry of Rites to have officials of the fifth rank and above to re-evaluate the matter. Yang Sijing, the Minister of Rites, suggested: According to the Laws of Posthumous Names, those who have made mistakes can be called "Gong", so please give him the posthumous name "Gong".
