《汉书·传·霍光金日磾传》
后来上书的人更加狡猾，全都使用密封奏事，皇上就叫中书令出来取走，不通过尚书，皇上越来越不信任我了。 
后上书者益黠，尽奏封事，辄下中书令出取之，不关尚书，益不信人。 
However, the people who wrote memorials later grew even more cunning. All of them sealed their memorials tightly, and the Emperor ordered the Master of Imperial Documents to take them away without going through the Ministry of State. The Emperor trusted me less and less as time went on.
