《汉书·志·地理志下》
郡中当初从辽东选取官吏，官吏看到百姓没有关闭隐藏的，等到商人去那裹后，夜晚就进行盗窃，民俗渐渐变得不厚道起来。
郡初取吏于辽东，吏见民无闭臧，及贾人往者，夜则为盗，俗稍益薄。
Originally, officials were selected from Liaodong, and when they saw that the common people did not close away or conceal their belongings, after merchants went there, they stole in the night, and the character of the people gradually became less honest.
