1. Language learning resources must specify proficiency level (A0/A1/A2) and medium (app/podcast/offline class) to prevent beginners from being discouraged.
2. "Phrase of the Day" posts are welcome with pinyin and usage context. Pure Chinese characters without annotation offer limited value to most users.
3. Share "successful communication cases" and "awkward misunderstanding stories"—real scenarios beat textbooks.
4. Paid language course advertisements are prohibited. Free resources and volunteer language partner matching are unrestricted.
