Thank you!

It's always good to know how to express one's appreciation in whatever language. Take note however, " xìe Xìe " is somehow less frequently used in Chinese in most situations. On campus, for instance, a teacher would not likely to say " xìe xìe " in Chinese when receiving a late homework from a student. As a matter of fact, " xìe xìe " would sound pretty odd to the Chinese ears in this particular situation. Wouldn't the teacher sound too much of a softball?

How " many " thanks ?  

Although "Xìexìe" is less frequently used in Chinese environment than in English, yet when indeed used in Chinese, it is often said several times. This repetition is a product in achieving phonetic convenience as well as semantic effect.
