In Chinese, there are many ways to say thank you. The most basic way is 谢谢 (xièxie) which is pronounced as syeh-syeh. Here are some other ways to say thank you in Chinese:

1. 谢谢你 (xièxie nǐ) - Thank you
2. 太谢谢你了 (tài xièxie nǐ le) - Thank you so much!
3. 你真是太好了 (nǐ zhēn shì tài hǎo le) - You are so kind!
4. 你最好了 (nǐ zuì hǎo le) - You are the best!
5. 你太客气了 (nǐ tài kèqi le) - You are too polite!
6. 感谢您 (gǎnxiè nín) - Thank you
7. 十分感谢您 (shífēn gǎnxiè nín) - Thank you very much!
8. 多亏你 (duō kuī nǐ) - Thanks to you
9. 爱你哟 (ài nǐ yo) - Love you!

I hope this helps! Let me know if there's anything else I can help with.
