Chinese cuisine includes styles originating from the diverse regions of China, plus styles of Chinese people in other parts of the world. Thehistory of Chinese cuisine in China stretches back for thousands of years and has changed from period to period and in each region according to climate, imperial fashions, and local preferences. Over time, techniques and ingredients from the cuisines of other cultures were integrated into the cuisine of the Chinese peoples due both to imperial expansion and from the trade with nearby regions in pre-modern times as well as from Europe and the New World in the modern period.
Styles and tastes also varied by class, region, and ethnic background. This led to an unparallelled range of ingredients, techniques, dishes and eating styles in what could be called Chinese food, leading Chinese to pride themselves on eating a wide variety of foods while remaining true to the spirit and traditions of Chinese food culture.
