Bowl wings are not shark fins, but shark fins are dried in the sun. Bowl wings are soup made by cutting lean meat into shredded pork, adding vermicelli similar to shark's fin, and then adding pepper and red vinegar. Because vendors usually serve them in small bowls in the street, they are called bowl wings. Bowl means small bowl in Cantonese.

Bowl wings originated in Hong Kong. In the 1960s and 1970s, many rich people in Hong Kong liked to go to restaurants to eat shark's fin, and then many shark's fin scraps were recycled and mixed with materials such as vermicelli, mushrooms and black fungus to make bowl wings for sale in the street. For a time, the big bowl of chicken wings has become a popular local snack in Hong Kong, and it is also called the four kings of Hong Kong snack industry together with fish eggs, car noodles and eggs. Before this, the big bowl wings have gradually appeared on the streets of Guangzhou and become one of the favorite foods of Guangzhou neighbors.

But now the bowl-shaped wing is a shark's fin soup, and its material is mainly vermicelli. Boil the soup with starch until it is thick, and turn brown by adding soy sauce and soy sauce, and add sesame oil, Zhejiang vinegar, white pepper, Chili oil and so on.
