I bought social security, but later resigned. What about the money deducted by the company every month?

All the endowment insurance premiums deducted from you every month go into your personal endowment insurance account. If you resign, you can transfer to the whole country. Medical insurance premiums also enter your personal medical insurance account and can also be transferred nationwide;

The accumulated payment of endowment insurance must be at least 15 years, and you can retire when you are old; Medical insurance, if you don't pay it at work, you won't enjoy it (until the money in the medical insurance card runs out). If you retire to medical insurance, the regulations vary from place to place. Some require men to pay for 30 years and women to enjoy retirement medical insurance for 25 years (some require 25 years for men and 20 years for women).

As for how much money to pay each month, the standards vary from place to place, and the situation of paying money in the unit and paying money independently is different.
