What does tea soup mean?

Tea soup is a traditional snack in Beijing. According to legend, tea soup originated in the Ming Dynasty, and it was named tea soup because it was taken with hot water, just like making tea. Tea soup mainly includes Shandong tea soup and Beijing tea soup. Tea soup is made from a big copper pot with a long mouth. When the water boils, the whistle next to the copper pot lid makes a "whoop" sound. The master who makes tea soup has a bowl in one hand and a copper pot in the other. The spout tilted downward, and a stream of boiling water rushed into the bowl, and the tea soup was full of water. The main ingredients of tea soup are glutinous rice noodles (sorghum rice noodles) and millet noodles, and the seasonings are brown sugar, white sugar, shredded green, red silk, sesame seeds, walnut kernels, assorted preserved fruits, raisins, Beijing cakes and pine nuts. Wash the glutinous rice flour with boiling water into a thin paste, and add various seasonings to eat. It tastes sweet, smooth and delicious.
