Can the social security paid in Hangzhou be transferred back to my hometown?

Legal analysis: Yes. First of all, you need to find the unit that accepts your old-age insurance procedures and handle the transfer.

Legal basis: Article 19 of the Social Insurance Law of People's Republic of China (PRC), if an individual is employed across the overall planning area, his basic old-age insurance relationship will be transferred accordingly, and the payment period will be calculated cumulatively. When an individual reaches the statutory retirement age, the basic pension is calculated in stages and distributed uniformly. Specific measures shall be formulated by the State Council.
