For example, I used to work in Gangxia and live near Haiya, Baoan, and the 395 business I received was very good. I always stand during the basic commuting hours!
Some drivers can get 4,000-5,000 yuan/month, but you should know that driving is a very tiring job, and you can't be distracted during working hours. The pressure is quite great!
Finally, I wish you success in your work in Shenzhen!
