Why do parents only pay attention to grades and never teach their children how to protect themselves outside, how to safeguard their rights and interests and how to communicate with all kinds of people? Because children's life is relatively simple, their contact with the outside world is mainly school, and they don't have much contact with society, so parents won't teach you how to deal with various things in society, which will distract your study energy and may bring you trouble. Parents care about their children's academic performance, hoping that their children will have a bright future, be admitted to a good university and find a good job in the future, so I think parents' feelings are understandable. As for how children can protect themselves and protect their rights and interests outside, parents will simply tell their children that they will not be completely ignorant.
