There are many ingredients, large choice space, good quality and low price, and with the atmosphere of the street, it feels different. The love of street snacks has been in our genes since ancient times. Snack food came into being as early as the pre-Qin period. Later, due to the influence of agricultural and mulberry festivals, festivals, historical events, anecdotes of celebrities, folklore and other factors, snack food emerged continuously. In the Tang Dynasty, snacks similar to ice cream were invented in ancient times. The name of this snack is "Sushan". According to the literature, the bottom layer of Sushan Mountain should be ice, covered with cream and ghee, and decorated with flowers and colorful trees. In Song Dynasty, snacks were often associated with desserts. In Song Dynasty, the word "sweet food" appeared in Wu's Zhong Fu Lu, which means dessert. In the Yuan Dynasty, the word "from eating" appeared in the Complete Works of Household Necessities by Anonymous, referring to cakes and snacks. But the word "snacks" really appeared in the Ming and Qing Dynasties. The twelfth time in the Qing Dynasty's Mirror Flower Garden mentioned that "after one or two rounds of wine, small dishes and bowls are served, and their names are called' snacks' in the south and' hot fried' in the north." The snacks here are more non-dinner snacks. In the Ming and Qing Dynasties, after years of development, snacks gradually developed into the system we see today, and the four famous snacks were formed in the Ming and Qing Dynasties. These snack groups bring together snacks from all over the country and form their own characteristics. The emergence of snacks must be based on the social needs of grassroots people at the beginning. Snacks are not a kind of dinner, because they are low in price and small in weight, and can be used as temporary food to satisfy people's hunger. The street snacks and food shops we see now generally do not have exquisite storefronts or meticulous services. However, street snacks have a short production time and low cost, and gradually become a favorite food of the broad masses of the people.
