《周书·列传·卷二十三》
因此前代君王告诫说： 一个农夫不耕种，天下必定有人因此挨饿；一个蚕妇不纺织，天下必定有人因此受寒。 如果这三个季节地方官员不注意审时度势，而使百姓荒废农业生产，这样就等于断绝百姓的性命，把他们赶向死路一样。
故先王之戒曰： 一夫不耕，天下必有受其饥者；一妇不织，天下必有受其寒者。 若此三时不务省事，而令民废农者，是则绝民之命，驱以就死然。
Therefore, previous emperors warned: If one peasant does not cultivate his farm, there will definitely someone starving because of it; if one silkworm farmer does not spin, there will definitely someone suffering from cold because of it. If local officials do not pay attention to the circumstances and let the commoners abandon agricultural production during these three seasons, they are equivalent to cutting off the commoners' lives and driving them towards the path of death.
