When I came to Changzhou, I had to taste the casserole fish head of Tianmu Lake in Puyang City. This is a traditional Jiangsu famous dish. It is said that the fish caught in the Tianmuhu Reservoir staff gave the guests a drink, but the fish was too big, so the owner threw away the fish head with a small amount of meat. Later, the old secretary of the reservoir, Xu Yugen, felt sorry, and put the fish head back. Cook the soup in the pan. After several years of exploration, the fish head of the soup is more and more delicious, the soup is thick and the aroma is overflowing, and the people who tasted it are all amazed. Since then, this casserole fish head has become famous.
