If you are a non-deep household, you can not pay social security at the age of 50, and you have reached retirement age. If it is a deep account, you can pay in one lump sum. If you can't pay, you can postpone the payment and get a refund. This age is not suitable for commercial insurance. If it is not a deep household, it is recommended to combine commercial accident insurance with rural cooperative medical insurance, which is characterized by low premium and can be completed through fixed investment funds.
