From Chapter 120 of Shi Yukun's "Three Heroes and Five Righteousnesses" of the Qing Dynasty: "Now all the good brothers and virtuous brothers have gathered together to show off the powerful and powerful people in the past and insult the heroes and sages. Unconsciously, it is shameful again. It’s ridiculous.”

It is true that today’s social environment is complex and there are too many temptations, and it is understandable that people should be more vigilant and protect their families. But if parents watch too closely, it will be difficult for their children to develop a healthy personality, and they will easily become "eating old people" when they grow up. Too much involvement between husband and wife will make each other tired of family life, and eventually they will lose trust and attachment to each other.
