Hello, this is a specialty of Zhongshan, Guangdong. I'm from Shunde, Foshan next door. My father likes it very much, so we often buy it. However, this kind of fish depends on the season, and it is usually introduced in hot pot in winter. If the whole fish is sold in our market, it costs 15 yuan per catty, 18 yuan for operation, and the restaurant will pay about 25-30 yuan for hot pot.
