The leader is right, the taste is from Huaiyang cuisine. And it's "mandarin fish", not "mandarin fish".

Mandarin fish (Siniperca spp) belongs to the order Perciformes, family Siniperidae, subfamily Siniperca, and genus Siniperca. Commonly known as: mandarin fish, season fish, mandarin fish, mandarin fish, mandarin fish. English name: Chinese perch.

Squirrel mandarin fish is a famous Huaiyang dish. Sweet and sour mandarin fish is a home-cooked dish. Because I don’t have such a big pot for frying fish at home, and even if I did, I wouldn’t be willing to waste a pot of oil just to have a bite. I had no choice but to fry instead of frying. In addition, if tomato sauce is not available in small places, the next best thing is to use vinegar instead. Back home, sweet and sour mandarin fish should be included in "home cooking".
