Almost in Xi 'an, as long as someone lives, there will be sticky soup. Walking in the back streets in the morning, you can smell the smell of broth coming from the cauldron everywhere, and hear the master selling sticky soup shouting in the distinctive Shangshan dialect: sticky soup, hot steamed bread, etc. And look at the rows of soup pulled up by the wooden spoon. This is the custom of Shaanxi people and the life of xi people. Secondly, bean juice is a unique folk snack in Beijing, which has been circulating for thousands of years. It is made of mung beans, with dim color and sweet and sour taste. It is often difficult to swallow for the first time, but once you taste a few mouthfuls, its pure and honest fragrance will make you want to stop. No wonder many old Beijingers who are far away from home are obsessed. When people drink bean juice, they often mix it with fried foods, such as inby, fried dough sticks, crispy skin, pork chops or spicy pickles.
