1. I bought three pieces, weighing one catty. The weight of a fish is about 160- 170g. Clean the bought fish, and the stomach and cheeks are the key cleaning objects for later use.

2. Chop ginger, onion and coriander respectively. Onions must be cut into small discs, not big, and parsley should not be cut too big. Tofu should also be cut into small pieces, not too much, 10 to 8 pieces is enough, because wild grass carp is not big.

3. Open fire, add vegetable oil, preferably vegetable oil, and add washed fish when the pot is hot. When the fish's stomach is open, turn it to the other side so that the fish won't smell fishy.

4. Then add a small amount of onion and ginger and stir fry with the fish. Be careful not to move too much when cooking, and be careful to break the fish. Add proper amount of cooking wine and vinegar.

5. Then add water, be sure to put enough at a time, avoid adding water in the middle, and then cover and boil. After the water is boiled, turn to low heat and cook for another 30 minutes.

6. Then add tofu slices and cook with the fish for about 10 minutes. Add the right amount of salt.

7. Finally, add spare onion slices and coriander. After the pot is boiled again, it can be served. It's delicious. It's delicious.
