When someone help you, you can say that :xiè xiè nín 谢谢您
It is correct English to say "thank someone for something" eg "My wife and I thank you for your kind invitation to your daughter's wedding"
thank you
When someone says congratulations to you, or when someone congratulates you, say, "Thank you".
you say:"Thank you so much for this invitation"
just say "i thank for giving me an opportunity to do this ,it it was a pleasure."
Thanking someone for yesterday infers that someone actually gave you yesterday. It would be better to say, "Thank you for making yesterday special."
Say Thank You for helping me in return..
Say "Thank You".
you could say Thank You
You say 'You're Welcome'
You say thank you
Thank you.
