Can Fuyang social security be used in Hangzhou? In addition, the company does not pay medical insurance now. Can it be re-paid when working in another company in the future?

Isn't the five risks combined now, but I don't know if there is any local policy in Fuyang. I suggest you ask Fuyang social security.

If you are insured in Fuyang, you should report it back to Fuyang for reimbursement, not in Hangzhou.

You can transfer to Hangzhou. You can transfer if you are insured in Hangzhou first. Hangzhou will open an admission notice for the elderly and medical care, and then get Fuyang's social security and medical insurance. If you don't pay medical insurance, you don't need medical insurance.

If you go to another company, you can generally pay medical insurance, but you can't make up for it.
