Everything QQ, WeChat, Weibo and Baidu Quietly Give Away

A platform-by-platform map of China’s internet — what QQ, WeChat, Weibo, Xiaohongshu, Zhihu, Douyin, Baidu, QCC and Tianyancha each expose, and how analysts extract it.

If you're doing serious OSINT on China, you need to understand that traditional tools and methods won't work. Platforms like Google, Facebook, and Twitter don't operate in China. Instead, local alternatives — each with its own structure and data — offer huge OSINT opportunities. To succeed at country-specific intelligence gathering, you have to know the domestic platforms.

Below, we go platform by platform — QQ, WeChat, Weibo, Xiaohongshu, Zhihu, Douyin, Baidu, QCC and Tianyancha — and exactly what each one exposes.
