How about social security, medical insurance, endowment insurance and provident fund in Beijing before switching from Beijing to Shenzhen? The new company gave me another social security in Shenzhen.

1. Personal pension insurance and medical insurance leaving Beijing can only be transferred and cannot be withdrawn;

2. The provident fund paid in Beijing cannot be withdrawn except for the part paid by individuals in rural areas, and only the provident fund paid by individuals can be transferred;

3. The personal contribution of your Beijing provident fund is transferred to the city where you work and can be merged with your original provident fund. After you buy a house, you can withdraw cash with the receipt of the house payment.
