Clean duck, brush and soak with soy sauce about ½ hour, reserve the soy sauce.
Deep fry the duck until it looks brown and the skin is crispy. Remove duck from frying pan and drain oil.
Put the duck in stew pot or the same fry pan. Add green onions, ginger, star anise, wine, the above remaining soy sauce, and 5 cups boiling water (to barely cover duck)
