Carassius auratus changing knives: wash the bought fish and remove gills, scales, internal organs, intestines and so on. Especially the black film in the belly of fish must be scraped clean. This film has a strong fishy smell and should be washed with clean water. Change the oblique knife from the fish head and cross the incision.

Pickled crucian carp: put the fish in a bowl, add 2 tablespoons of cooking wine, 2 tablespoons of soy sauce, and add half a spoonful of salt to melt. Rub the whole fish body with shredded ginger dipped in juice and rub the belly several times. Finally, put the shredded ginger in your stomach.

Dip shredded ginger in egg white and smear it on the fish, including the place where the knife is changed. Roll the fish in flour, so that the whole fish is covered with a layer of raw flour (including the inside of the incision)
