How about Hefei Silver Shield Guard?

Their headquarters is in Luosigang, where my classmate worked after leaving the army.

There's nothing mysterious about it. Basically the same as ordinary security guards. I've been inside. They used 97- 1 riot guns.

I get up early every day and go to various banks to get boxes, which are full of money. I take them out of the bank at night and keep them in a unified way.

Salary 1300 or so, with insurance. Other treatments vary from bank to bank.
