fq-book is an online Chinese-language book and documentation project focused on VPNs, proxies, tunnels, and related internet access technologies. Rather than being a single executable program, it is structured as an educational repository that explains concepts, tools, configuration approaches, and network behavior.

It uses Docsify for online presentation and can be deployed through GitHub Pages or viewed locally. ...
