《资治通鉴·汉纪·汉纪五十》
灵帝还喜好积蓄私房钱，收集天下的各种奇珍异宝。每次各郡、国向朝廷进贡，都要先精选出一部分珍品，送交管理皇帝私人财物的中署，叫做 导行费 。
帝好为私稸，收天下之珍货，每郡国贡献，先输中署，名为 导行费 。
Emperor Ling also liked to accumulate private money and collect all sorts of strange and exotic treasures in the world. Every time each of the commanderies and kingdoms sent tributes to the imperial court, they first had to select a portion of rare treasures to be sent to the Zhongshu, which was responsible for managing the emperor's personal finances, and was called "guidance fee".
