Snacks were recorded as early as 1500 years ago. There are many kinds of snacks in every corner of every region. Local snacks also have local characteristics. Special snacks are often made from local materials, which can highlight the local material culture and social life. Nowadays, snacks are more than just things to fill your stomach between meals. Snacks pay attention to fresh ingredients and making methods just like dinner, and some of them are even more complicated than dinner. Therefore, many restaurants pursuing higher profits are reluctant to sell snacks.
