Looking for reliable connection into china behind great firewall, VPS, VPN or good proxy?

I am looking for VPS server in mainland china or reliable proxy connection which is behind the firewall, I need it for testing my websites.
Does anybody know about something. All proxies or clouds offer chinese servers but problem is they are usually owned by west companies like LeaseWeb, that is why they are not really behind the firewall.
I can buy hundreds of proxies for example from Webshare.io, they offer chinese proxies, but they are all managed by west companies and they are not behind firewall. A lot of VPNs are the same.
Alibaba cloud offer VPS servers but as western citizen you are allowed to buy only hong-kong servers nothing in mainland china.

I am looking for real ip behind chinese firewall for testing things.

Thank you

try a pm or 2 to some of bhw proxy sellers

Maybe in this case that is better to find someone in China to test your services?
I assume you can pay for that kind of activity instead of paying for VPS. Perhaps you will be able to find such helpers on freelancer or other places.
