《明史·志·卷四十三》
孝宗特别注意控制束缚，所以命令整顿了好几次，然而宦官骄横放肆已经很久，长期以来形成的习惯递相沿袭，不能禁止最初，太祖制定宦官服饰，他们的纱帽与众臣不一样，而且没有上朝时戴的朝冠、幞头，也没有祭祀时穿的祭服。
孝宗加意钳束，故申饬者再，然内官骄姿已久，积习相沿，不能止也。初，太祖制内臣服，其纱帽与群臣异，且无朝冠、幞头，亦无祭服。
Emperor Xiaozong paid special attention to controlling and restraining, so he ordered rectification several times. However, the eunuchs have been arrogant and presumptuous for a long time. The habits formed over a long period of time have been handed down from one another and cannot be prohibited. Initially, Taizu formulated the eunuch's clothing. Their gauze caps were different from those of the ministers, and they didn't wear court caps or hoods when in court, nor did they wear sacrificial clothes when offering sacrifices.
