datawhalechina/leedl-tutorial ? reverse-engineered prompt

I want a clean Chinese learning site for 李宏毅深度学习教程 that lets people read the full tutorial online, browse the chapters by topic, and quickly jump to things like CNN, Transformer, BERT, GAN, diffusion, reinforcement learning, and so on.

Please make it feel easy to study, with a simple home page, a table of contents, chapter pages, and a clear place for errata and PDF download links. It should also surface the homework and example code so students can follow along and practice. Use the existing content in the repo and make the reading experience polished on desktop and mobile, with nice navigation and readable formatting for long technical notes. If you need to look up current docs or best practices online, go ahead.
