Is there an official flight attendant in Tianjin subway station?

Tianjin subway station attendant has no official. They are all recruited through open recruitment, and some are entrusted to third parties. They all sign labor contracts, and they are all contract workers. Only managers are regular employees, and the treatment will definitely be better. The employees of the third-party hosting company do not directly sign contracts with the light rail group, but only sign contracts with the hosting company, and their wages are paid by the hosting company.
