My own tilapia is like this, 1. Clean up the fish and remove the black film. Cut both sides of the fish and marinate in soy sauce. 2. Cut the onion, ginger and garlic into two sections with the back of a knife. Shred the onion, shred the onion, shred the ginger, cut the ginger into small pieces, and mince the garlic. 3. Take the pot, wipe the bottom of the pot with a large piece of ginger to prevent it from sticking to the pot, add a little oil, heat it, add shredded onion and ginger, minced garlic, stir-fry it, add fish, turn it upside down after a little discoloration, then don't turn it over, add warm water, and make it slightly flat with the fish. When the pot boils, add wine and vinegar, and add salt. Pour it on the fish, then use two shovels to face it slightly, and it will be cooked in two or three minutes. If you like, you can thicken the remaining soup with starch, pour it on the fish, and then add coriander, which will feel better.
