Shanghai hukou social security broke off to buy a house?

Is your spouse a Shanghai hukou or a foreign hukou? If the spouse is registered in Shanghai, it doesn't matter if the social security is interrupted for one month.

If the tax bill is interrupted for one month, you can make it up with the tax bureau, and consult the tax bureau for details.
