Bawangsu, formerly known as -su, also known as Xiaosu, is a traditional famous snack product in Wujiang Town, Hexian County, with a history of nearly a thousand years. According to legend, during the Chu-Han contention, when Xiang Yu, the Overlord of Western Chu, broke through Sikuishan (now Simashan) and fled to Wujiang, he felt hungry and thirsty. At this time, an old man was selling -su near the city and offered Xiaosu to Xiang Yu to satisfy his hunger. Since then, people have renamed -su to Bawangsu. Bawangsu is made of flour, sesame, vegetable oil, sugar and other raw materials. It contains a variety of essential amino acids and vitamins for the human body, and has the functions of appetizing, moistening the lungs, strengthening the spleen and strengthening the body. There are two kinds of salty and sweet. When eaten, it is crispy and fragrant, with unique color and taste, rich in nutrition, sweet but not disgusting, and oily but not greasy. The inheritance history of Bawangsu is simple and clear, and its production process has never been lost. First, it is due to the local admiration for the Overlord of Western Chu, and second, as a folk snack, Bawangsu is delicious, portable and affordable, and is deeply loved by the people. As a tourist product, Bawangsu has participated in various exhibitions and trade fairs many times, and has also been selected as a gift by relevant departments. Its development prospects are broad.
