* Wo xiang nian ni: This means "I miss you".
* Xie xie: This means "Thank you".
If you want to express "I miss you, thank you", you can say:
* 我想念你,谢谢你。 (Wǒ xiǎng niàn nǐ, xiè xie nǐ.) - This is a more natural and correct way to express the sentiment.
It's important to note that the literal translation of "Wo xiang nian ni Xie xie" would be "I miss you thank you", which doesn't make sense in the context of expressing gratitude for something someone has done.
