As the saying goes, people see profit without harm, and fish see food without catching people. What do you mean by not knowing how lucky you are in the water?

This shows a phenomenon that people do something just because it is good for themselves, and they don't think about what harm it will bring to themselves. Fish swim in the water, only see the bait on the hook, but not the hook behind. People don't know the meaning of a lucky boat in the water when they are blessed. This is also the case. At present, the conditions are already very good, but they are not satisfied. They always feel that their conditions are not good.
