I work in Beijing, but the contract and social security are in Shenzhen and there is a branch office in Beijing. Is there a difference in social security between Beijing and Shenzhen?

Dear, different social security purchase areas will have a great impact. First, medical insurance reimbursement, such as working in Beijing and buying social security in Shenzhen, will be reported in different places, and the proportion will be reduced. Second, the impact of settling down and buying a house, Beijing and Shenzhen have relevant requirements for settling down and buying a house, depending on where you finally want to develop and choose.
