This isn't really true. No matter how good the VPN, it can always be determined that someone is using it as the traffic the government monitors will be encrypted. The Chinese security services can then just knock down that person's door. If the government is as determined as China's,.even VPNs won't stop them.
I am in China and I can tell you the China Telecom ISP assigned to me knows exactly that I have vpn and that I always have vpn when I am in China. The ISP does all kind of interference and obstruction yet my vpn continues to function. So kindly refrain from telling me what is true and not true, fact or false thx.
There are always times I have to connect to the vpn service site for remote assistance using the regular ISP here and I do connect, get the remote assistance and get the vpn reconnected and soundly reestablished. It goes in cycles of the Party censors devising a new attack technology and my vpn provider putting its engineers to it and whacking back the Party censors with a sound and solid vpn connection again.
I and Chinese people themselves know well the pigs, er, Party-Government authorities can come pounding on our door yet they never do. When I do have to get a China Telecom ISP service tech the guy always says my problem would stop if I quit using vpn and stopped accessing YouTube, Facebook, Washington Post etc etc among the hundreds of sites that are prohibited or, even worse, forbidden.
Different words of the Party-Government censors appear when a Chinese or a foreign devil are accessing a blocked site. "Unavailable" is just any old site the censors block, such as Reuters. "Prohibited" is a site one can get the ISP disconnected for continually trying to access, such as the China Uncensored website. "Forbidden" is a hot site that censors will singe your ass for by cutting the China ISP provider from you -- MSNBC is a "forbidden" because it bashes Trump by the minute; CNN likewise. Fox is a China favorite one can access any time because it defends Trump. My vpn accesses all of 'em even sometimes when I need service from the vpn website. Censors mostly use their own China networks such as China Telecom, China Mobile and others to interrupt the programing itself given Party-Government censors can't stop the vpn riding the China network ISP. So censors disrupt their own network they control absolutely.
Of course Party-Government censors know I use a vpn. I use a vpn based in USA that is China specific (Express VPN) and Party-Censors know which one I use and other use. However, if the Party Mind Control Police hauled off everyone in China that used vpn they'd have a hundred million Chinese and foreign devils such as myself locked up. Workplaces and schools wold be missing people they need. So it's too much for the Party-Government to do. The Boys do scare off some Chinese from using vpn, but only a few. Plus using wifi means the mind control police have to check out too many people to find the one using vpn. Or the two. The three etc. So you trying to tell me and readers what is true in China and not true in China makes you look pretty stupid. Maybe you should ask rather than try to issue ex cathedra disrespectful and numbnuts pronouncements.
Chinese and foreign devils alike know that when response time gets slow then the censors are into the script with their corruption tactics to include spyware and malware. Reboot, reconnect to your vpn and continue. Rinse and repeat as necessary. I'm connected to vpn now.
Censors are highly effective getting into your antivirus system that we pay for. That's where they go first. Any antivirus system that does business with offices in China has to play the game and give censors access. McAfee is one such cooperator with the censors that nobody in China subscribes to any more. China has its own free antivirus system, 360, which the Party-Government installs in all its browsers and sites via its ISP networks and that control where Chinese can go and must not go. Baidu is corrupt with censorship among a slew of other Chinese homegrown websites. China bought Opera and now that browser is corrupt as all hell. This info is easy to find out via using networks, browsers, security systems etc or by word of mouth in China. It's a given to Chinese never to trust a China browser, search engine, network ISP etc. None of 'em and not ever.
