Can I only get a pension without paying social security after retirement?

After the old-age insurance payment reaches 15, when you reach the legal retirement age and go through retirement procedures, you can receive the old-age pension without paying social insurance premiums. However, if your basic medical insurance is less than the payment period (generally 30 years for men, 25 years for women or 25 years for men and 20 years for women), you need to continue to pay (or pay in full at one time) to enjoy the basic medical insurance benefits for retirees.
