Is it Yes or No ? - The China pecularities

An interesting point about the Chinese language Vs the English Language can be demonstrated by the following sentence structure

Question : You havent had food as yet ? The answer to this if you havent had food will be "No". But if you ask a chinese this question he will answer in affirmitive "Yes" which means Yes I havent had food.

This creates a typical confusion in the minds of the westerners.
