Is it true that Pudong Airport recruits ground crew?

Shanghai Airport Ground Service Co., Ltd., a joint venture between Pudong Airport Co., Ltd. and China Southern Airlines, is the only company in Pudong Airport that may recruit ground services. It is a company that operates across Hongqiao Pudong. If it is not in the name of this company, other recruitment is a gimmick of the intermediary company of the labor service company, and it will not sign a contract with the local service company, which belongs to the nature of labor dispatch.
