《旧五代史·后梁·列传四》
在这以前，河朔三镇掌握官府钥匙、负责洗抹扫地的都是阉人，罗绍威说 ：这种人都只能供宫禁中驱使，哪是人臣家中能蓄养的。 
先是，河朔三镇司管钥、备洒扫皆有阉人，绍威曰： 此类皆宫禁指使，岂人臣家所宜畜也。 
Prior to this, eunuchs from the three towns of Heshuo were responsible for holding the keys to official offices and for cleaning and sweeping. Luo Shaowei said that such people should only be used as servants in the imperial palace and should not be kept by government officials.
