In September 2020, a photograph went viral on Chinese social media. A Tsinghua University student was cycling across campus, laptop balanced on his handlebars, typing while he pedaled. Someone captured the image and posted it with a single word: neijuan. Involution. A system folding in on itself. The photograph was viewed a billion times.

This episode traces how China built the most extraordinary social mobility machine in human history—and why it's breaking down. Coverage spans the 1985 village classroom to the 2024 "last generation" declaration, including: the Gaokao exam system and its psychological toll, youth unemployment (official 21%, actual estimates higher), the "lying flat" and "let it rot" movements, demographic collapse (birth rate below Japan's), the Kong Yiji literary meme and its censorship, and what happens when 400 million young people conclude the ladder is broken. Runtime: ~2 hours; 18,000 words. Sources include China National Bureau of Statistics, Peking University surveys, CSIS, Brookings, MERICS, South China Morning Post, Caixin Global, and Chinese-language Weibo discourse analysis. Transparency note: Episode uses composite characters (Chen Wei, Liu Xiaomei, the Zhao family) constructed from documented patterns and reported experiences.
