Why can't rural social security be found in Chu tax system?

Hello, you can't use the inquiry and self-payment on the Chu tax pass. The reply is as follows: Chu Tax Pass APP and social security payment are the responsibility of the tax bureau, and cannot be paid by APP. You can call jiangling county Taxation Bureau at 07 16-4 156599 for consultation. You can call jiangling county Social Endowment Insurance Service Center (07 16-4732006549) to inquire about the payment of endowment insurance.
