Prepare the chicken wings. Slice the wing along the bone in order to leave the skin and meat attached. Sever the first joint of the chicken wing and remove the bones. Holding tight to keep the joint intact, slide the knife along the underside of the skin and separate all the way to the joint. Season each chicken wing inside and out with salt and pepper and marinade for 1 hour in the fridge.

For stuffing: Heat up frying pan, add some oil. Stir fry chopped onion until fragrant. Add carrot, celery, and spring onion until half cooked, season with salt and chicken powder. Put aside to cool down.

Take out marinated chicken wings from the fridge and stuff each one with stuffing ingredients. Do the same until the last one.

Pan fry each chicken wing until the skin turns brown. Arrange the fried chicken wings on a plate.

Make the sauce: In a bowl, mix soy sauce, oyster sauce, sugar, salt, and sesame oil. In a wok, add the mixture for the sauce and cook until boil. Add corn starch mixture and stir until the sauce thickens. Pour the sauce over the chicken wings. Serve hot.
