Confucius said: The winner has three pleasures, and the loser has three pleasures. Music festivals, rituals and music, the kindness of Taoist people, and more virtuous friends are beneficial. Fun, fun, fun, fun is harmful. (Chapter 5 of Historical Records) Confucius said: There are three kinds of beneficial happiness and three kinds of harmful happiness. It is beneficial to take the adjustment of rites and music as happiness, to praise the strengths of others as happiness and to make more virtuous friends as happiness. It is harmful to regard pride and luxury as happiness, travel as happiness and feasting as happiness. Confucius believes that there are three kinds of happiness that are beneficial and three kinds of happiness that are harmful. The advantages and disadvantages lie in the pursuit of what kind of happiness. Confucius did not object to people's pursuit of happiness, physical and mental happiness. He likes playing the piano and singing, rituals and music to adjust his spirit and make his mood happy and peaceful. He likes to publicize the advantages, achievements and contributions of others, and he has made more good friends. These preferences are certainly beneficial. He believes that one of the harmful hobbies is "taking pride as fun", that is, taking pride as fun. For example, in the Nanjing Massacre, Japanese soldiers took pleasure in killing people, while rogue gangs took pleasure in bullying the weak. The second is "leisure travel". Of course, we are not against games, play and entertainment. We also develop tourism and encourage citizens to travel during holidays. This is a combination of work and rest. After intense work, I can adjust my spirit through traveling so that I can work better in the future. If you use your vacation to gamble and go whoring, it is a "trip". Thirdly, it's normal to have family dinners, get together with friends, drink some wine, sing, dance and engage in some recreational activities. However, everything must be measured and not excessive. All improper entertainment activities must be banned.
