Hello: I am coach Xing Yongxiang (driving technician) from Dong 'an Driving School in Tianjin. Now I will answer your question as follows: At present, most driving schools in Tianjin contract coaches to every coach, and every coach can set up a registration office to recruit students in the society. Remember that no matter which driving school you apply for, you must sign a training agreement with the driving school coach and ask for a receipt stamped with the official seal of the driving school.
