How to marinate fish is as follows:

1. Clean the fresh fish, cut it in half or cut it into pieces of appropriate size.

2. Sprinkle appropriate amount of salt and sugar on the fish and knead evenly. If you like a stronger taste, you can also add some five-spice powder and other seasonings.

3. Add appropriate amount of cooking wine and soy sauce, add ginger slices and garlic slices at the same time, and mix evenly.

4. Put the fish into a sealed bag or a glass container, pour in the marinade and soak it in it. If using a Ziploc bag, squeeze out the air and seal the bag tightly so the fish can better absorb the marinade.

5. Put the marinated fish in the refrigerator and refrigerate it for 6-8 hours, or marinate it directly at room temperature for 2-3 hours. Marinating time depends on the size and thickness of the fish.
