《资治通鉴·汉纪·汉纪二十》
六月，元帝下诏： 朕顾念到民众饥寒，远离父母妻子，从事不是他们本行的工作，保卫君王不常居住的宫殿，恐怕不是促进阴阳合和的办法。
六月，诏曰： 朕惟烝庶之饥寒，远离父母妻子，劳于非业之作，卫于不居之宫，恐非所以佐阴阳之道也。
In June, Emperor Yuan issued an edict: I am concerned that the people are starving and freezing, far away from their parents and wives, doing work that is not their specialty, guarding palaces where the emperor does not often reside, which is probably not the way to promote balance between yin and yang.
