《资治通鉴·汉纪·汉纪七》
朕屡次颁下诏书，每年都鼓励百姓种植，至今未见成效，这就证明官吏没有认真地执行诏令去勉励百姓。
吾诏书数下，岁劝民种树而功未兴，是吏奉吾诏不勤而劝民不明也。
I have repeatedly issued edicts encouraging the people to farm each year but until now I have not seen any result and that proves that the officials have not seriously carried out my edicts to encourage the people.
