Punching in each other means helping each other to punch in during the live broadcast of Tik Tok, increasing the interaction and traffic between live broadcasts. This behavior is actually self-deception, because it can't really bring effective traffic growth. Punching each other is only superficial interaction, and it can't really attract valuable audiences and fans. On the contrary, too much punching each other will gradually abandon the account, because there is no real increase in real traffic and fan base. When starting a business in Tik Tok, we should pay attention to providing valuable content and attracting real audiences, rather than relying on the false interaction of punching each other.
