Does Shenzhen still recruit security guards for large-scale properties? How is the treatment?

I heard that there are still many places to recruit security guards in Shenzhen, but some good property requirements are still relatively high. You can look at the websites and contact information of these enterprises on the Internet and call yourself to ask. Shenzhen is still quite chaotic. Don't trust people easily. Security is more difficult to do now, but if you really want to do it, it should be no problem.
