The difference between Zigong social security and Chengdu social security

There is no difference. Zigong social security and Chengdu social security are at the same level. Chengdu Social Security and Zigong Social Security are both social security bureaus under the unified leadership of Sichuan Social Security Bureau. When purchasing social security, everyone implements a social security policy, and the purchase grades are different. The pension received after retirement is different, and the medical insurance reimbursement is exactly the same. So there is no difference between Zigong social security and Chengdu social security.
