A Chinese-language security teaching page that demonstrates dynamic routing, wildcard DNS, QR-code entry points, multi-hop redirects, attribution reporting, and anti-debugging behavior.

The page insists this is a classroom simulation, but its lesson plan includes rotating subdomains, signed download links, masked sensitive addresses, fingerprinting, cookie handshakes, and a real-looking app download flow. It is an unusually detailed specimen of how legitimate security education and suspicious redirect infrastructure can occupy the same page.
