if you don't know or doubt how popular VPN is used in China, it indicates that you know little about modern China. everyone I know uses VPN or know how to use VPN if they need. as for exact scale, I'd leave that to you. you could easily figure that out as there are ton of such information online.

If brainwashing really worked greatly like you said, Soviet Union would still exist now. It was their people who overthrew Soviet Union.

exactly because of China going through the disaster like Cultural Revolution, many people just don't believe these propaganda anymore.

my point was not there is no brainwash. it's everywhere including China and US. my point was in the era of Internet and the popular use of VPN in China, i don't think the brainwash really works greatly like you'd think.
