Observing all kinds of relatives and friends means that "strict father is a dutiful son". I don't understand why there are loving fathers and dutiful sons. Children who are used to love have no future.
This sentence is aimed at the current social situation in China. We have been infected by Confucianism for thousands of years and are deeply rooted. Maybe you will see some educational models from overseas education, such as persuasion education and kindness education. Of course, I also believe them, but in the following social observation, I found that they are not suitable for our big environment in China. Even this model is not more effective than "filial son under the stick". Of course, it is not without exception. After all, people are so different. I'm just describing a common phenomenon. "strict father gives birth to a dutiful son" really suits China's national conditions.
About fatherly love, in China, our thoughts are closely related to our education, and most people in China are traditional people. Under such education, people's psychology has been suppressed since childhood, the pressure of study and face, and so on. It makes people feel very rebellious. If a loving father doesn't take care of it, then most people will release their rebellion, which will cause the phenomenon you see.
