Remove the scales and gills, and then wash the fish and cut off the head.
Slice open the fish along the bone on both sides, but don’t cut off the tail.
On the side of the fish skin, cover with cooking wine and saltwater, then roll on dry starch.
Put the fish into a pot with hot extra virgin olive oil and fry until golden, do the same thing with the fish head. Put the body and the head into the shape of a whole fish.
Leave extra virgin olive oil in the pan, fry the scallions, add tomato sauce, sugar and soy sauce. Add diced boiled vegetables.
