Describe people not to be too greedy, but to know what to give up.

"Tao Te Ching" Chapter 44 "Who is the counterpart of name and body? Which is more important, health or goods? What kind of disease is acquisition or death? If you love it very much, you will pay a lot, but if you hide it too much, you will die. Therefore, knowing enough is not humiliating, knowing that it is not dangerous can last for a long time. " Chapter 46, "There is a road in the world, but it is in vain; There is no way in the world, and the suburbs have horses. Sin is greater than desire, blame is greater than desire, and disaster is greater than dissatisfaction. So contentment is enough, and it is enough. "

Many people just understand contentment as knowing that contentment is always a pleasure. It is more passive and complacent to define happiness on the desire to get and satisfy, and to define the meaning of satisfaction unilaterally. The happiness brought by such satisfaction can't last long.

What Lao Tzu wants to tell us is when to stop desire, how to stop desire, and what will happen if we don't stop endless desire in time. Long-term prosperity can only be achieved by knowing the prosperity obtained by satisfaction.
