I cannot create audio or video files (vietsub and piyin are usually associated with video/audio content). However, I can provide you with 5 short dialogues using the phrase "为我们的友谊干杯!" (Wèi wǒmen de yǒuyì gānbēi! - Cheers to our friendship!) Each dialogue will include pinyin and a rough English translation. Remember that tones are crucial in Mandarin and are not perfectly represented by pinyin. **Dialogue 1:** * **A:** Zhège wǎnshang zhēn hǎo! (这个晚上真好！ - This evening is really nice!) * **B:** Shì a! Wèi wǒmen de yǒuyì gānbēi! (是啊！为我们的友谊干杯！- Yes! Cheers to our friendship!) * **A:** Gānbēi! (干杯！- Cheers!) **Dialogue 2:** * **A:** Wǒmen yǐjīng rènshi hěn jiǔ le. (我们已经认识很久了。- We've known each other for a long time.) * **B:** Duì a, wǒmen de yǒuyì zhēn kěguì. Wèi wǒmen de yǒuyì gānbēi! (对啊，我们的友谊真可贵。为我们的友谊干杯！- Yes, our friendship is precious. Cheers to our friendship!) * **A:** Gānbēi! (干杯！- Cheers!) **Dialogue 3:** * **A:** Xièxie nǐ de bāngzhù! (谢谢你 的帮助！- Thank you for your help!) * **B:** Bú kèqì! Wèi wǒmen de yǒuyì gānbēi!

Remember to practice pronouncing the pinyin with the correct tones for a more authentic experience. You can find tone markings (e.g., mā, má, mǎ, mà) in many online pinyin dictionaries or learning resources.
