Can I buy residents' medical insurance after buying social security?

Dear, I will give you an answer now: you can also buy residents' medical insurance if you buy social security. Taking Xuanzhou District as an example, according to Article 8 of the Interim Measures for the Administration of Basic Medical Insurance for Urban and Rural Residents, all urban and rural residents who have registered in this city or have lived in this city for more than 1 year and have not participated in the basic medical insurance for urban workers, including rural and pastoral residents, urban non-employed residents, all kinds of full-time students, preschool children and other personnel stipulated by the state and autonomous regions, can participate in urban and rural residents.
