Online companies that recruit technical training or join in the name of Zhou Heiya or other brands are often not regular companies, and most of them are fake well-known brands or unknown brands. This truth is also well understood-how can a well-known brand easily transfer its own brand or technology to others by opening its own shop to make money? Only those who can't make money by opening a shop will try to cheat foreigners. So when you see this kind of advertisement, you must pay attention to screening and be careful.
