Investigate its reason, I estimate that there are several:
First, I don't want to be disturbed too much. Public figures seem glamorous, but in fact they are full of difficulties. For example, you will recognize them wherever you go, reply to enthusiastic fans, sign autographs, take photos and greet each other. It takes a lot of effort to encounter this scene dozens of times a day. Who can stand it?
Second, establish members. Nobody knows who you really are. Just like in the movie "Spider-Man", you are a member of all beings on weekdays. In case of emergency, Spider-Man will be used to deal with it. The advantage of this is that even if you screw up, no one knows who you are in reality, and you can continue to change your avatar.
Third, create a sense of mystery. A fierce cat is a typical example. People who sign him up for tens of thousands of dollars can't see him in person, which is unique all over the world. I am an ordinary person, I can't understand, I can't learn, and of course I don't want to learn.
I still prefer online celebrities, such as Luo Yonghao, Luo Zhenyu and Li, who expose themselves to the public and dare to say and do. They are more like human beings.
