I bought social security in Shuangliu, Chengdu.

Social security can be transferred and merged with the transfer of people's workplace. It is the social security paid by the insured in the household registration. You can apply for social security payment in the service hall of the social security bureau of your household registration with your ID card, unemployment certificate, household registration book, social security card and bank passbook. For social security paid intermittently, you can apply to pay according to the local minimum payment base, or you can pay at a high level.

If your original social security is not paid by the insured in your household registration, you can't apply for supplementary payment, and you can only renew the social security through the employer, which will not affect your accumulated payment period.
