? My social security card is from Shenzhen, and now I work in Zhongshan. Can I buy social security in Zhongshan with my previous card? What is the procedure?

When your social security is transferred out of Shenzhen, you have to change your card and change it to Zhongshan Social Security Card. You need to transfer out in Shenzhen first, and then transfer to Zhongshan. Let the original unit transfer your social security to the internet first, and then go to the social security bureau. If you do it yourself, just bring your ID card, social security card and transfer application form. If you entrust others to do it, write an application for entrustment! Then turn it in and it's OK!
