"Use seven points wisely and leave three points for children and grandchildren", which is probably the experience summed up by the ancients in real life. Because there are many uncertain factors in people's fate and they are used to the foolish offspring of smart people, they have to make such feelings. Why do people often say that people should not do things too well and leave a way out for themselves? I think the word "absolute" has two interpretations here. First, too reckless, regardless of other people's feelings, there is no room for manoeuvre; Second, it is very wonderful, and the attainments in a certain aspect have reached the peak, which is unparalleled. The former seems to happen to ordinary people, because it is meant for ordinary people. The second difference. It's for those extraordinary people. They are all famous for their unique skills, but they can't feel happy and perfect because of their success, because they will have an unsatisfactory child, who is often far from their parents' IQ. From this point of view, it seems that the previous generation used up all the wisdom of the next generation, that is, doing nothing, leaving nothing to make future generations proud, leaving only a kind of sadness. Genetically, it may be a genetic problem. If explained in a superstitious way, it can only be interpreted as "seven points are very smart and three points are descendants", that is, nothing can be done too well, otherwise the consequences will be unimaginable.
In short, people can't live too smart and wonderful, and it's easy to be annoying.
