Practice: fry the oil and ginger in a red-hot pot, then fry the fish head in the pot until golden brown, and drain the water.
The amount depends on the amount you want to drink), then boil the water, put all the herbs in when the water boils, and then cook it again (about 2-3 minutes)
Clock will do), and then pour all the soup in the pot into the stew pot, and it will be OK.
