Hello poster: Wuchang fish is a specialty of Ezhou, Hubei. It is a piece of bream. It is still a legend, saying that Chairman Mao passed by Ezhou, Hubei when he went for a swim in the Yangtze River. He would rest when he was tired. When it was time to eat, the waiter brought a dish, which was Wuchang fish. After Chairman Mao finished eating, he repeatedly said, "Yes, it's delicious." He also wrote a poem. I can't remember the details. It seems that there is a sentence in the middle: ' He drinks Changsha water and eats Wuchang fish, so Wuchang fish is famous all over the country. It is still a specialty of Hubei. The answer is that only the Wuchang fish from Fankou Gate in Ezhou, Hubei is authentic, and there are very few of them now.
