Why can't Beijing prove the endowment insurance investigation letter?

It is obviously difficult for Beijing to ask the social security center of the household registration place to issue a certificate of not paying social security in the household registration place.

It is impossible to give you this kind of investigation letter!

It is a joke to let an unrelated unit issue relevant certificates.

I suggest that you quickly move your household registration to Shenzhen, and then apply for a local household registration in Shenzhen to retire. This can avoid this knot.
