How about being a Guangzhou subway station attendant in 21?

It's very hard for college students who have just entered the station. For station attendants, they will go to the station after training and get their employment certificates, and then they will have the opportunity to be promoted continuously. First, the station attendant, then the duty officer, then the stationmaster on duty, followed by the dispatcher or stationmaster who can take the exam. . The treatment includes two insurances, one gold and a year-end bonus. The company has regulations that can't be disclosed. Thank you.
