What is the principle of mobile phone hegemony?

The popular explanation of mobile phone hegemony is short messages that occupy the whole screen. The actual principle is to send the short message to the user's mobile phone point-to-point through the background system of Star Qingyun Channel, and the screen pops up. No matter what the user operates on the mobile phone, there will be a short message that the user likes very much, which will not be saved like traditional information. After reading it, it will disappear automatically. There are not so many spam messages, but enterprises also like it, and users will certainly be able to read it, which is better than other publicity methods. I don't know if you said that.
