Is the recruitment of special car drivers in China reliable? Can the deposit be refunded in the end?

I am the driver of the Shenzhou special bus in Harbin. I started to work on April 24, and I got paid at one time. The salary is good! The deposit is refundable. One of my teammates resigned for family reasons. First, I gave him a refund of 8000 yuan. After a month, the vehicle was not suspected of violating the law, and then he was refunded 2000 yuan. Finally, he uploaded a picture to prove it. This is six days' salary in April!
