The sour soup is an old Beijing-class summer drink, and during hot seasons, most people buy oome from the procession (which is also used to replace oome with Yang Mei) with a little sugar to sour and ice to drink. The raw materials for sour plum soup are u-mei, mountains, cinnamon, licorice and sugar. This Draft says: “The one who picks half-yellow is made of fumes.” It removes the heat and cools the pain, even treats cough, cholera, dysentery, and the mythical novel, The White Snake, writes about the disease. The soup is diarrhea, silt, thirst, pneumoconiosis, constant drinking and treatment of disease, and strong health care, which is rare in hot summers。
