The earliest people who ate shark fin were fishermen. After the fishermen sold the shark's meat, they would stay with them to eat shark fin, which is shark fin. The shark fin is very delicious because it contains a kind of fin rib, which is rich in nutritional value, but most of its nutritional value can not be absorbed by our bodies, so it is often used as a precious cooking raw material, and the types of shark fin are also very wide. In our daily life, we can divide it into two categories, namely, sparred wings and scattered wings. Shark fins can also be divided into different grades according to their colors, such as yellow, white and gray, among which the quality is better.
Shark's fin is widely produced in China, in some coastal provinces, such as Guangdong, Fujian and Shandong, and in some Asian countries, such as Japan, Thailand and the United States. Among the shark's fin imported from China, the Philippine shark's fin is the top grade. In some parts of Asia, eating shark's fin is a very common cultural phenomenon. Shark's fin is made by drying, drying in the sun, then soaking in lime water and forming according to a series of processing. As a precious species, sharks have been banned from hunting on the high seas in some modern areas, such as the United States.
