According to my cooking experience, the steps of stewing fish are as follows:

1. Preparation of ingredients: Wash the fish, remove scales, gills and viscera, and cut into thick slices for later use.

2. Fried fish: put oil in a hot pot, add onion, ginger and star anise, and stir fry until golden on both sides.

3. Cook the fish: add boiling water, boil over high heat and simmer for 35 minutes.

4. Seasoning: After the soup is thick and white, add cooking wine, salt, chicken essence, pepper and cooking oil to taste, put it in a bowl and sprinkle with coriander.
