Why we included this project

If your team is tired of just stringing together API calls and wants to actually understand what happens under the hood, this Chinese-language curriculum is worth a look. It walks through roughly 500 lessons in 20 phases, starting with linear algebra and machine learning fundamentals and moving up through transformers, LLM engineering, and multi-agent systems. The build-it-then-use-it structure stands out: you hand-write algorithms in plain code before reaching for PyTorch or a framework, so the libraries stop feeling like magic. Each lesson also leaves you with something reusable, whether that is a prompt, an agent loop, or an MCP server. The site is not a machine-translated mirror either; it localizes lesson text, quizzes, and diagrams, has a searchable companion website, and includes narrated math videos. Treat it as a structured study path or onboarding plan, not deployable software.
