[Shadowdh]

hi there all, I am looking for a good 成语 to express gratitude and thanks for providing support and help in getting students to China to learn Chinese. I was wondering if anyone knows of a good one to use. Many thanks for any help offered...

感激不尽 is totally ok

type 感谢 成语

but i think some of them might seem a lilltle exaggerated

Thank you very much for that. Also for the search term, I have been puting in something different. Helps to know what to use.

If you wanna express your graditude and thanks to someone, does that mean it was impressive and unforgettable? If so, here we have 沒齒难忘 (mo4 chi3 nan2 wang4).

沒齒 = getting old enough to lost all the teeth

难忘 = unforgettable
