1. The Story: Wang's Accidental Discovery
Wang, a young professional, wanted to learn Python for work and also find Math videos for his elementary school nephew. Commercial courses were expensive, and YouTube/Bilibili often distracted him with entertainment.
He stumbled upon www.dxzy163.com. First impression: "Is this website from 1999? It's just a wall of text links." But after clicking around, he was shocked:
- Python: Systematic tutorials, chapter by chapter.
- K-12 Math: Organized by grade level.
- Bonus: He even found lectures on history and gardening.
"It's an unpolished treasure chest!" Wang exclaimed.

5. Conclusion
