I am a rural hukou in wutongqiao district, Leshan City. I used to buy social security in the factory for five years, but now it has been interrupted for several years.

You can only buy one kind of social security, either rural social security, resident social security or employee social security. You must be an employee in the factory, so even if you resign, you can go to the social security center to hand it in yourself. You can make it up in a few years, and then send it to the new unit when you work. If you buy this again, and then buy social security for residents or rural areas, it will only be one of them when you reach retirement age. Then the other one came for nothing.
