I used to work in Wuxi, but now I work in Changzhou. I have a household registration in Changzhou. What information and procedures are needed to transfer from Wuxi to social security?

According to the Administrative Measures for the Transfer and Continuation of Social Security Relations, which came into effect on 20 10/month, you can now handle the transfer of social security relations from Changzhou to Wuxi. The specific process is as follows: when you leave your work unit in Changzhou, ask your unit to open a social security payment voucher at the local social security center to get back the old-age insurance manual for you, and then give it to the human resources management department of your work unit in Wuxi, and the human resources management department will go to Wuxi Social Security Center to handle the transfer formalities for you.
