I cannot directly create Vietnamese subtitles (vietsub) and Pinyin for audio or video content. I need the audio or video of "Nín guìxìng" to do that. However, I can give you 5 short conversations in simplified Chinese characters, Pinyin, and a *rough* approximation of Vietnamese translation, keeping in mind that perfect translation requires understanding context and nuance. The Vietnamese is intended as a general idea, not a precise, polished translation. **Conversation 1:** * **Chinese (Simplified):** 你好！(Nǐ hǎo!) * **Pinyin:** Ni hao! * **Vietnamese (approx.):** Xin chào! (Hello!) **Conversation 2:** * **Chinese (Simplified):** 你叫什么名字？(Nǐ jiào shénme míngzi?) * **Pinyin:** Ni jiao shenme mingzi? * **Vietnamese (approx.):** Tên bạn là gì? (What's your name?) **Conversation 3:** * **Chinese (Simplified):** 谢谢！(Xièxie!) * **Pinyin:** Xiexie! * **Vietnamese (approx.):** Cảm ơn! (Thank you!) **Conversation 4:** * **Chinese (Simplified):** 对不起！(Duìbuqǐ!) * **Pinyin:** Duibuqi! * **Vietnamese (approx.):** Xin lỗi! (Sorry!) **Conversation 5:** * **Chinese (Simplified):** 再见！(Zàijiàn!) * **Pinyin:** Zaijian! * **Vietnamese (approx.):** Tạm biệt! (Goodbye!) To get actual vietsub and pinyin for "Nín guìxìng" (which I assume is a specific audio or video clip), you would need to provide that audio or video to a service or person who can create subtitles and add pinyin. There are online tools and professionals who can do this for you.
