"Knowing the gains and losses of advancing and retreating" is Liu Bang's famous saying.

If a person wants to gain wisdom and wealth, he needs to make unremitting efforts and struggle. , his parents accumulated tens of millions of wealth for him without any effort and struggle, so he spent all day doing nothing and walking like a zombie. Very few people like this live a long life. There are also people who grew up in a poor family and suffered from hunger and cold. They have to run around all day long to make a living. They are calm, comfortable, and happy, and they live a long life. There are also a very small number of people who have obtained a lot of wealth in a short period of time through corruption, deception, abduction, robbery and other unfair means, but they still live long. People who are on tenterhooks, fearful, hiding here and there, afraid of being discovered, afraid of losing their wealth, and whose thoughts are always under inexplicable pressure will not live long. This is a manifestation of "gain" and "loss".
