I used to buy five insurances and one gold in Beijing, but now I want to transfer to Qingdao. Where should I change trains?

First go to Qingdao, the social security bureau of the district government where your new company is located, and handle the acceptance letter (letter of introduction) of social security transfer. Then, take the letter to Beijing and go through the social security transfer formalities at the social security bureau or citizen center where your previous company is located. After the transfer, you will be given a social security payment certificate, and you can take it to Qingdao Social Security Bureau for handover. (It may take one month, please consult Qingdao Social Security Bureau for details). The Social Security Bureau in Beijing is willing to issue relevant social security certificates. (In the absence of Qingdao social security admission notice, consultation is also needed to see the different policies in the province. Zhejiang used to need to transfer the admission notice, but now it is not needed. You can directly open a social security certificate in the social security bureau of the district government where the original unit is located, and then hand it over to the social security bureau of the new unit.
