Although the store's history is not long, the sour plum soup it provides has the simple and sweet flavor of the past. It has become one of the must-try snacks for tourists visiting Tamsui. The boss inherited his mother's traditional method of making sour plum soup, using plums along with roselle, chrysanthemum, ginseng, licorice, and mint, among other herbs, to brew a rich and sweet soup. Especially on hot summer days when thirst is unbearable, drinking it feels exceptionally refreshing and cooling, even more so than typically sweet beverages or sodas. No wonder it quickly became a drink that every tourist must have. Recommended product: Sour Plum Soup.
