First, in the wider world, the group is a concentration camp for a certain kind of people, especially the technical students who have just started. Asking questions is on the one hand, and on the other hand, you can get to know many real experts through groups, but experts generally talk less, but they speak just right. If it's not for this purpose, you should join the group cautiously. Sometimes I join a group on a whim and get tired of it in a few days. On the contrary, you hate this group being talked about all the time. But it is not recommended to quit immediately (except for a few people). We can temporarily block the group news. Because you want to find someone to step on the space in the future, or publish your own website, blog and job search, you can also use these groups.
Second: shrinking society. Everyone in the group, like a small society, is very helpful for college students who have just started their career to learn how to let others tell you information and how to make others not tired of you. After all, the network is not completely virtual.
