These words all come from Laozi's "Tao Te Ching"
Chapter 48 of "Tao Te Ching": For learning, one grows day by day, and for Taoism, one day loses. Damage after damage, to the point of doing nothing. If you do nothing but do everything, you will always have nothing to do to win the world; if you have something to do, it will not be enough to win the world.
Chapter 80 of "Tao Te Ching": In a small country with few people, it is necessary to have a few weapons but not use them; to make the people die again and not move far away. Although there are boats and carriages, there is nothing to take them; although there are armor and soldiers, there is nothing to display them. Let the people re-knot the rope and use it. To the extreme of treatment, the food is sweet, the clothes are beautiful, the house is safe, and the customs are happy. 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.
"Tao Te Ching" is a classic work of Taoism, with eighty-one chapters and more than 5,000 words. When Laozi retired and passed through Hangu Pass, Guan Yin, the gatekeeper, detained Laozi and asked him to write down what he had learned in his life. This is the Tao Te Ching.
Doing nothing and doing everything is the main idea of ??Lao Tzu, which means not to force things to violate objective laws, but to let nature take its course and let things develop and grow naturally.
A small country with few people is an ideal society described by Laozi. It reflects the self-sufficient lifestyle pursued by ancient Chinese people. I fantasize about returning to the primitive social state without oppression or exploitation.
