VPNs increasingly don't work well, however, it's not like they completely turn a blind eye. It's some kind of statistical thing that drops connections that "look wierd" that can interfere with even quite obfuscated VPNs.
yeah, actually what I told 'VPN' is also included like SS/SSR/V2Ray/Xray/Trojan, which is easily gotten, and smooth link and you can even have a HK phone number and used the no GFW network in China.
