How about Shenzhen Jindi Property as a security guard?

Not so good. Come to Beijing to show off the new Silicon Valley as a security guard. After three days, you will not be a security guard. There is no overtime pay on holidays, don't mention it. If you come, you won't deduct your salary. When you become a captain, you have to invite the supervisor to dinner, pay the phone bill, buy cigarettes for breakfast, and surf the Internet. Anyway, everything is the responsibility of your captain.
