Are you a daughter or a son? You are so careful that you should be a daughter. In order to show filial piety, you can also make some iced sour plum soup for your father at home during the summer vacation. If you do it yourself, your father will like it better.

The method is simple. Mume, hawthorn, licorice, rose hips or dried tangerine peel are all acceptable. Put these in the pot and add water. Bring them to a boil with high fire, and then simmer slowly. It will be fine when the water is only half. When it cools down, put them in the refrigerator and it will become iced sour plum soup!
