My social security was originally bought in Chengdu Shuangliu, but I didn't work in that unit anymore, so I left it alone. Now I work in Chengdu, Dan. ...

If Shuangliu belongs to Chengdu social insurance co-ordination area, there is no need to transfer the social insurance relationship. After the original work unit stops insurance, the new work unit will register social insurance and continue to pay social insurance premiums.

If Shuangliu and Chengdu are different social insurance co-ordination areas, according to the provisions of the Social Insurance Law, if an individual is employed across co-ordination areas, his basic old-age insurance, basic medical insurance and unemployment insurance will be transferred accordingly, and the payment period will be calculated cumulatively. After the new work unit is registered, with the consent of the new social insurance institution, it will go to the original social insurance institution to handle the transfer of social insurance relationship, and go to the new social insurance institution to handle the transfer and continuation of social insurance relationship with the transfer-out certification materials and related documents.
