《旧唐书·列传·卷八十八》
杨国忠恃宠专权，又希求名声，大多征召各州县农民，让他们铸钱，农民既不是本行当的工匠，被差遣他们的人逼着服役，多数遭受鞭打责罚，人人都过不下去。
国忠恃权宠，又邀名称，多征诸州县农人令铸钱。农夫既非本色工匠，被所由抑令就役，多遭箠罚，人不聊生。
Yang Guozhong relied on his favor to monopolize power and seek fame, so he mostly conscripted farmers from various states and counties to cast money. Farmers were not craftsmen in this line of work, and those who were sent to serve were forced to do so, and most of them were beaten and punished. Not everyone could survive.
