If you just want to drink the soup, you can choose to mash the fish, so that it can be stewed into a milky white color. If you also want to eat fish, then heat the oil, add ginger slices and green onions, and then fry the fish on both sides. It is slightly yellow, pour water and make it milky white over high heat. (Mash the fish in the same way, fry it and then cook it over high heat.) It is best if you have bone soup. If you don’t have it, just use water. If you have bone soup, just use medium heat< /p>
