Chinese institution/service that can confirm company.

Like in topic:
I'm want confirm that comapany/internet shop is real and is registered in China.
Is there any website or other service that can in legit way confirm me that online?

that would be difficult I imagine. Your best guess would be to search for the shop/institution online and confirm yourself the validity of the business, check their address under "contacts" that will give you an idea where they are based and by searching their address you'll probably find information related to legal registrations
