## Overview

This repository is a Chinese-language, hands-on AI engineering curriculum with a companion interactive learning site and certification tracks. The main learner workflow is to choose a learning goal or course, study explanations and runnable experiments, then practice through quizzes and project work; the README also describes optional AI mentor skills that read course material and track progress. The graph groups the course by broad subject, while retaining notable implementation examples and the site client. Relationships are limited to those documented in the README or visible in excerpts; the API handlers and most course implementations were not sampled.
