I'm from Miyun, and I want to apply for social security myself. How to operate?

You can continue to pay in the social security account you paid before. Those who are less than 15 years old need not pay. Under the age of 15, it can be paid until retirement age 15. Individual contributions only need three insurances, namely, endowment insurance and maternity insurance. Medical insurance is estimated to be around 600 per month. You can go directly to the social security window for consultation and payment.
