Where does the Shanghai subway security inspector recruit?

Look for neighborhood committees and public employment agencies in your area. I participated in an interview with subway security today, which was informed by the neighborhood Committee. But the salary is not high, the minimum wage 16 10, the attendance award 100, and nothing else. I have two days' early shift and two days' middle shift. Unless the minimum wage is adjusted, it will always be 16 10. I don't understand, what's good about this job except stability? !
