I started paying Social Security (including hardware) in November 2007 and paid it through January 2009. If I stop paying social security now how will it affect me in the future?

Social security does not expire for how long you stop paying.

Containing five insurance, should be the unit for the social Paul, after leaving, the original unit will be suspended, by the local town account, you can turn to the town of flexible employment social security to continue to pay the pension insurance and medical insurance, and so on in the same city to find a new job, but also can be transferred to a new unit for the renewal of social security, even if there is a suspension of arrears of fees, before the social security are valid.
