Frequently asked questions
Absolutely. The course is designed for beginners (HSK 1-2), focusing on basic terms like 机器 (machine), 零件 (parts), 维修 (maintenance). You'll learn through real-world scenarios, no complex background needed.
Yes. You'll practice phrases for giving instructions, asking about specs, and reporting machine status. To become fluent, you'll need extra practice, but the course gives you a solid foundation for daily situations.
