[Wait, instruction says "Không phóng tác", so just translate directly].
* *Formatting final output.* (Proceeding to generate content).
*(Self-Correction during final output generation)*: Ensure tags are clean. No wrapper.: The text says "Mạn Đầu Sơn" which translates literally to "Steamed Bun Mountain". I will use "núi Màn Đầu" as a proper noun to stay consistent with the "Hán Việt" rule and not translate the meaning directly unless necessary for the joke, which the text explains anyway ("đều là cái bánh bao...").
Looks solid.
