Where does Wujiang perch come from?

In the Western Jin Dynasty, there was a Fu Mao (from Wujiang, Ying Ji) named Zhang. He is an official 3,000 miles away from home. Whenever the autumn wind rises, he thinks of the bass in his hometown. In order to taste the bass in his hometown, he gave up his official position and returned to his hometown of Wujiang. This is proved by his poem: "It's a pity that the Wujiang River is full of water and perch is fat since the autumn equinox." After this incident, it was spread as a much-told story. Perch feed on fish, shrimp, etc. It is very big, 0.6 meters long, with small black spots on its back and dorsal fin. It lives by the sea, spawns in the estuary where salt and fresh water meet in early spring, grows rapidly, and swims into Danshui River in autumn. Perch is a natural raw material, so it should be cut and eaten. Its delicious taste and firm meat are widely spread all over the world. In Songling Town, Wujiang City, there is a 20-mile-long river that leads Taihu Lake from the Grand Canal to the Yangtze River and into the East China Sea. It is called Wusongjiang (Songjiang for short) and is famous for its rich bass. There is a suspended Hongqiao and a suspended rainbow pavilion on Wusong River. Scholars from Song Dynasty and later generations came to Wujiang to admire perch, and often climbed the Hung Hongqiao to admire autumn scenery, intoxicated with the Hung Rainbow Pavilion. When poetry flourished, it left many kind words about perch. For example, Su Dongpo, a great writer, intoned, "Ying Ji is really better than Weng Ding and is also a sage of bass." Mi Nangong (Mi Fei), a great calligrapher, said in a poem, "Jade broken perch and frost orange, rainbow and autumn spread all over the southeast." Because of their praise, Wujiang perch is famous. Chen Yaozuo, Prime Minister of Longtuge in the Northern Song Dynasty, praised Wujiang River as the hometown of perch in his poem "Boating on the Shore, Autumn Wind Setting the Sun". During Song Xining's reign, Wujiang County ordered Lin to build a "perch pavilion" to be the hometown of perch. Nowadays, Chinese and foreign tourists come to Wujiang to taste bass. (Suzhou)
