Wash the chicken wings and drain the water. Pour the corn oil into the pot and fry the chicken wings to golden on a small fire. Add ginger slices and stir fry, add water, and soak the water to two-thirds of the chicken wings. Add oyster sauce and wine, add a little salt, and boil over high heat.
Cover the lid and turn to a low heat for about 10 minutes to see the soup reduced. At this time, turn to the fire to collect juice.
