A small country with few people. It makes the people have a rare weapon but does not use it; it makes the people die again and not move far away. Although there are boats and carriages, there is nothing to ride on them; although there are armor and soldiers, there is nothing to display them. Let the people re-knot the rope and use it. Enjoy your food, enjoy your clothes, live comfortably, and be happy with your customs. Neighboring countries look at each other, hear the sound of cocks and dogs, and the people do not interact with each other until they grow old and die. ——Lao Tzu

——Mencius
