How long does it take for Dongguan social security to stop paying for one year and renew it at the original factory?

If you stop paying social security and then renew it, if you don't stop paying halfway, it doesn't matter and it doesn't affect the use. If the payment is interrupted and re-paid, it will have an impact on medical insurance, maternity insurance and unemployment insurance.

If the network is disconnected for subsequent payment, the medical insurance paid by the company will not enjoy the treatment until next month 1 day, and the individual payment will have to wait for 3 months to enjoy the treatment. Unemployment and maternity insurance need to be paid continuously for more than 1 year and re-insured to enjoy the benefits.
