📖《网络代理与VPN应用详解》 详细阐述代理、隧道、VPN运作过程，并对GFW策略如：地址端口封锁、服务器缓存投毒、数字验证攻击、SSL连接阻断做相关的原理说明
A Chinese-language book explaining how internet censorship circumvention works — proxies, VPNs, tunnels, GFW mechanics, and tool configurations. It's aimed at mainland Chinese developers and users who want to understand the why behind the tools, not just which button to click. Hosted as a Docsify site on GitHub Pages.
The GFW coverage is technically honest: it explains DNS poisoning, RST injection, SSL blocking, and IP/port blocking as distinct attack categories rather than hand-waving at 'the firewall'. The scope is wide — SSH tunnels, Shadowsocks, V2Ray, WireGuard, Tor, IPFS — and each section includes actual config snippets, not just screenshots. The repo is extremely lean at 144KB (images hosted externally on postimages), so forking and self-hosting is painless. Actively maintained with a July 2026 commit.
The content is almost entirely Chinese, which cuts off the majority of developers who'd otherwise find the technical GFW analysis useful. Some sections reference tools that have been abandoned or blocked (GoAgent is long dead; Heroku free tier is gone), and these haven't been removed, just left to age. The repo is a book, not a library or tool — you can read it, but there's nothing to import or run. Organization across 50+ markdown files is navigable only through the sidebar, which becomes unwieldy as the topic count grows.
