Shanghainese food
Wontons are a kind of dumpling with a meat center inside a thin skin that is made of flour, egg, water, and salt. The Shanghainese kinds come in two sizes, "small" and "big". The small wontons are wrapped loosely by hand and eaten for breakfast. The big wontons are wrapped carefully and eaten for lunch or dinner. Both kinds are often filled with minced pork and bok choy and served in chicken soup, but restaurants sometimes have as many as 50 different fillings. A well-known special kind is "Three-Freshness Soup"  sānxiān tāng), made with pork, shrimp, and fish.
