《资治通鉴·唐纪·唐纪六十一》
文宗说： 朕知道中书舍人不应当越职规劝，鉴于你有谏臣的风采，所以，要让你屈尊担任谏官。 
上曰： 朕知舍人不应复为谏议，以卿有诤臣风采，须屈卿为之。 
Emperor Wenzong said: I know that the Zhongshu Sheren should not overstep his authority and persuade him, but in view of your integrity as a minister of advice, I want you to condescend to be an official of advice.
