Oysters have always been loved by gourmets, especially French oysters. Oysters are known as "milk in the sea". In fact, oyster farming has a long history in China. "Poet" Li Bai once wrote an inscription for oysters: "Oysters are the only one in heaven and earth". Oysters are delicious in meat and rich in nutritional value, and they are milky white after cooking. The quality of oysters abroad is excellent, while the island waters in China are rich in salty and fresh water resources. In order to improve and increase the variety of oyster culture in China, since the reform and opening up, China has introduced many oysters, such as Pacific oyster, Portuguese oyster and Kumamoto oyster. As the saying goes, "Eat a hundred kinds of oysters and drink a hundred kinds of water". Due to the changes in water quality and eating habits, these oysters have also formed different flavor characteristics, which are deeply loved by the people of China.
