《新唐书·列传·卷四十》
 臣以为国家的军旅每年出动，调度的费用习以为常地逐年增多，右边戍守四镇，左边驻防安东，国库空虚，辗转运输的车辆在路上往来不绝，服役在外的人时间长了，怨妇旷夫必然会多。
臣伏见国家师旅岁出，调度之费狃以浸广，右戍四镇，左屯安东，杼轴空匮，转输不绝，行役既久，怨旷者多。
I believe that the country's military expeditions and mobilisations increase year by year, and the costs of transportation and deployment become increasingly common. We garrison the four towns on the right and station troops in Andong on the left, the national treasury is empty, and the vehicles for transporting goods and supplies are constantly on the road. Those who serve in the military for a long time will inevitably have many resentful women and absent husbands.
