What is a good answer?

A high-quality answer is to give correct and clear answers to the questions raised by others, give real solutions to the questions raised, and give your own unique views. It is the person who asks the question who suddenly wakes up and knows how to solve this kind of thing. Respondents can't make things up for the sake of making up numbers, really answer the questioner's doubts, let his inner doubts disappear, and what he doesn't know become known.
