How do I use a VPN to connect into Mainland China's internet + firewall restrictions?

I used a vpn to try to connect to Mainland China, but it doesn't exactly work like Mainland China's internet, including China's firewall restrictions. When I went to Mainland China from February to June and refused to use a vpn, I realised even though I don't hate being on western social media, but for various reasons, I liked their internet restrictions better and I was happier. Is there a way to connect back there? Thanks.
