I think you can learn a lot from watching Tik Tok. Why do some people say Tik Tok is not good?

Part of it is that I don't feel any nutrition. Most small videos are just for fun, to kill time. Part of it may be because Tik Tok does have great influence. For example, in the dormitory, several people brush Tik Tok beside you, and when playing outside, their ears are full of magical sounds. Originally, they just had no feelings, which made them even more disgusted. But I personally like to paint Tik Tok's ...? The normal state of people now.
