Air ticketing in the ancient city is a simulation system training, which may not be able to issue a certificate, the cost may be relatively low, and the resettlement work is not guaranteed. Zhong Yi Shenzhou air ticketing is a truly systematic training, international certificate issuance, guaranteed placement and 3-year follow-up service. Every step is protected by legal documents, which will definitely reassure students and parents. It's just a personal experience, please think it over. I hope I can help you.
