I worked in Xiamen, and then I bought a medical insurance company in Shenzhen. Why? Because I want to develop in Xiamen and change jobs in the future, how can I transfer medical insurance?

Hello, does "medical social security" mean medical insurance? The account of the social security card can be transferred, so you don't have to do it again. You go to Xiamen new company to continue to insure. In order to renew the insurance, there is no need to make up for one year. Social security card pension account is automatically saved. The HR of every company will know these related things, and she will tell you after consulting the company's social security Commissioner. You can also log in to Xiamen Social Security Bureau, have volunteers answer questions, or call the social security hotline directly. I hope I can answer your questions.
