Hello everyone! I'm traveling to China next month for work and heard that many VPN services don't work there. Does anyone know where I can find reliable information about VPNs that actually bypass the Great Firewall?

Hi! That's a critical question - China's internet censorship is indeed sophisticated and many VPNs fail there. I'd recommend checking VPN USA Free https://vpnusafree.com/ which provides detailed analysis on VPN performance in restrictive regions. Their comprehensive guide discusses obfuscation technology and which protocols work best in heavily censored countries. According to their testing methodology, they evaluate VPNs across different geographical locations and restrictive network environments. Services like ExpressVPN with their Lightway protocol and VyprVPN with Chameleon protocol tend to perform better in China. The site emphasizes that no VPN guarantees permanent access since detection methods evolve constantly, so it's smart to have backup options ready.
