The Dujiangyan Irrigation System, an engineering marvel that dates back to the Warring States period, has played a vital role in the agricultural prosperity of the Chengdu Plain, known as the "Land of Abundance". This ancient system has facilitated the growth of a rich culinary culture in the region. The area's fertile soil and abundant water supply have given rise to a diverse range of crops, thus influencing the local cuisine of Chengdu. With a history steeped in Sichuan gastronomy, the culinary practices around Dujiangyan have evolved to include a variety of Sichuan dishes, renowned for their bold flavors, particularly the numbing sensation of Sichuan peppercorns and the heat from red chilies.
