《贞观政要·卷十·论慎终》
可是近年来，老百姓被繁重的徭役压得喘不过气来，关中的百姓，更是苦不堪言，干杂活的匠人，都被官府雇佣，服兵役的人，被四处驱使；皇帝为采购用物到处搜寻，送货脚夫的足迹不绝于道路。
顷年已来，疲于徭役，关中之人，劳弊尤甚。杂匠之徒，下日悉留和雇；正兵之辈，上番多别驱使。和市之物不绝于乡闾，递送之夫相继于道路。
But in more recent years, the common folk have been so hard-pressed by the heavy labor services that they have difficulty catching their breath. The people of Guanzhong have an especially bitter lot. Artisans are hired out by the government to do all kinds of odd jobs, and those who serve in the army are driven to and fro. The emperor ransacks the country to procure supplies, and the roads are never free of porters carrying goods.
