The Story of the Three Character Classic

Recently, I have been teaching my children to read the "Three Character Classic". As I read it with concentration, I found out a lot of new things. I found that every sentence contained simple truths about how to deal with others, so I compiled some of my superficial understandings. This is not an in-depth study at an academic level, but just some reading experience of ordinary parents. Please don't criticize it if you don't like it. After all, everyone has their own understanding.
