It's totally unnecessary. Listening to Lao Du's class is a set of principles that everyone often talks about, and it is also a set of nonsense. There is no practical application value at all. Everyone has different conditions. The EQ he said is just one of ten million possibilities. Not targeted. Generally speaking, the EQ of a big country must be plagiarized, or it is worthless to learn from a person. This is all a cliche. Let children see the world and meet all kinds of people.
