How to 繞過 網際網路審查 in Any Country

Governments use several technical methods to censor the internet:

• DNS blocking: ISPs are ordered to return false results for blocked domain names. When you try to visit a blocked site, you get an error or redirect. This is the simplest and most common form of censorship.
• IP blocking: The IP 位址 of blocked services are added to a blacklist. All traffic to those IPs is dropped at the ISP level.
• Deep Packet Inspection (DPI): 進階 firewalls (like 中國's 防火牆) analyze the content and patterns of network traffic to identify and block specific protocols (VPN, Tor, etc.).
• SNI filtering: When you connect to an HTTPS site, the domain name is sent in plaintext during the TLS handshake (Server Name Indication). Censors can read this and block specific domains.
• Bandwidth throttling: Instead of blocking services outright, some countries slow them to unusable speeds (making VPNs too slow to use).
• App store removal: Governments pressure app stores to remove VPN and circumvention apps in their country.

These tools are proven to work in heavily censored countries:

• Tor with 橋接: When direct Tor connections are blocked, 橋接 (unlisted Tor entry points) 繞過 the block. Pluggable transports disguise Tor traffic:
  • obfs4: Makes Tor traffic look like random data
  • Snowflake: Uses WebRTC proxies run by volunteers worldwide
  • meek-azure: Disguises traffic as Microsoft Azure connections - very hard to block without blocking Microsoft
• VPN with obfuscation: Mullvad (WireGuard + obfuscation), ProtonVPN (Stealth protocol), and Windscribe offer protocols specifically designed to 繞過 DPI.
• Psiphon: Free, open-source tool designed specifically for censorship circumvention. Automatically selects the 最佳 protocol (VPN, SSH, HTTP proxy) based on what works in your country.
• Lantern: Peer-to-peer censorship circumvention tool. Users in uncensored countries share their bandwidth with users in censored countries.
• Shadowsocks: A proxy protocol designed in 中國 specifically to 繞過 the 防火牆. Very effective but requires a server outside the censored country.

Recommended approaches for the most heavily censored countries:

• 中國: The 防火牆 uses the most 進階 DPI in the world. 最佳 options: Tor with meek-azure 橋接, Shadowsocks with a server in Japan/Singapore, or a VPN with obfuscation (Mullvad Stealth, Astrill). Download tools BEFORE entering 中國.
• 伊朗: Blocks Tor, VPNs, and many circumvention tools. 最佳 options: Tor with Snowflake 橋接, Psiphon (specifically optimized for 伊朗), or satellite internet (Starlink where available).
• 俄羅斯: Blocked 中的 Tor 2021 but enforcement is inconsistent. 最佳 options: Tor with obfs4 橋接, VPN with WireGuard obfuscation, or I2P network.
• 土耳其: Periodic blocks on social media and VPNs. Tor with 橋接 works well. Psiphon and Lantern are also effective.
• 埃及/阿聯酋: Block VoIP and VPNs. Obfuscated VPN protocols (WireGuard + obfuscation) and Tor 橋接 are the most reliable options.

Always use VPN + Tor together when bypassing censorship. The VPN hides Tor usage, and Tor provides anonymity that the VPN alone doesn't guarantee.
