It's different. Although Meishan and Chengdu are both in Sichuan Province, their social security systems and policies are different. Specifically, social insurance in Chengdu is managed by Chengdu Social Insurance Administration, including basic old-age insurance, basic medical insurance, unemployment insurance and industrial injury insurance. Social insurance in Meishan City is managed by Meishan Human Resources and Social Security Bureau, including basic old-age insurance, basic medical insurance, unemployment insurance and industrial injury insurance. The social security systems and policies of the two cities may be different, such as the payment ratio, payment base and social security benefits. If you need to know the specific social security policies and systems, I suggest you consult the relevant local departments or go to the local social security center for consultation.
