To a large extent, college students are more inclined to socialize online than offline. Probably the extremely tolerant social networking with masks spoiled these college students who shouldn't associate with others in reality. Why are you afraid of offline socialization? Because you are you offline. I am trying to be a "cute sweetheart" or a "world-weary devil" on the Internet, and there is no coat that the Internet gives me. Everyone knows your appearance, clothes, speech, voice ... everything will be exposed to everyone's eyes, but many times you are not your true self. The gap in real life makes some people unable to understand the real you, which leads to the emergence of "social fear" groups. In fact, fear is not the essence of offline social interaction, but because it takes a long time and energy to start a friendship, and it is also necessary to ensure that it is suitable for a period of time every time, and friendship may break down. Often sincere people will get more hurt, just like falling in love. This further promoted the prosperity of social networking. Almost zero-cost social networking meets the rapid and urgent spiritual desire of contemporary college students, which makes social networking emerge suddenly.
