Landlord: The Dada information consulting company you mentioned can provide medical visa services. It is the first professional institution in China to provide overseas medical information consulting services. I saw a special report about its company in the Global Times. They can provide one-stop services such as medical visa processing, appointment of medical institutions and doctors, airport pick-up and accommodation arrangement, medical translation and overseas air rescue. According to the needs of domestic patients. You can ask them how to contact foreign hospitals and how to handle medical invitations. I wish you good health!
