Junk mobile phone. Junk stuff, shameless money, Lei Jun and 360 boss are fellow villagers, all from a poor small place in Hubei, and their business is very irregular. One relies on hunger marketing, and the other relies on making rogue software. They are all disgraced businessmen. Especially Xiaomi mobile phone, advertisements are implanted everywhere. Is that MIUI system specially designed for advertising? Even TM's text messages have been implanted with many usury advertisements. Click to enter all the APP downloads of wealth management and usury; Especially at the bottom of the bank-related SMS page involving user privacy, there are various private usury advertisements. Do you want to cheat your customers of everything? In order to earn advertising fees, shameless businessmen use rogue means. Black-hearted manufacturers without any technical content and core patented technology will close down sooner or later, relying on branded garbage companies. Have a disgraceful past, doomed to a lifetime of shame, just a few stinky money.
