This repository is a collection of configuration files (Quantumult X rewrite rules) for ad blocking and UI customization across dozens of Chinese mobile apps and websites. The rules intercept network requests, reject advertising endpoints, modify API responses using JSON-jq expressions, or redirect traffic to remove promotional content. Key modules cover apps like Weibo, Amap, Bilibili, Netease Music, and Douban, as well as function scripts for YouTube ad removal, Bilibili subtitle conversion, and Emby media server enhancements. The architecture is flat: each .conf file is a standalone rule module that can be imported into Quantumult X. The repo is not a software application itself but a set of well-documented, actively maintained proxy configurations. There is no application code, data pipeline, or reusable library; the value lies in the precise, battle-tested URL patterns that demonstrate deep reverse-engineering of app APIs. The repo is highly specialized for Chinese app ecosystems and requires Quantumult X (or compatible proxy tools) to function.
The LLM identified 2 files worth highlighting for reuse:
Implements a custom search engine switcher by intercepting DuckDuckGo search queries and redirecting to 30+ specific engines (e.g., 'yt <query>' redirects to YouTube, 'db <query>' to Douban, 'cn' switches App Store region). The pattern uses regex-based URL rewriting with capture groups, demonstrating a non-obvious use of proxy rules to create a powerful command-line-like search interface in Safari. This is reusable as a template for any custom URL redirection system.
Uses a 302 redirect to strip ad-related query parameters from YouTube video stream URLs, effectively blocking video ads. The pattern '^(...)/redirector...$1$2$3' is a clever technique to remove 'ctier=L' and similar parameters while preserving the rest of the request. Combined with response-body scripts for browse/next/player endpoints, it provides comprehensive YouTube ad removal. The approach is reusable for any service where ad parameters can be identified in request URLs.
