In a large bowl, add the salt, sugar, light soy sauce, oyster sauce, cooking wine, dark soy sauce, and 1 teaspoon of white pepper over the chicken wings and mix until the marinade has coated all of the wings.
Cover with a plastic wrap and let it marinade in the refrigerator for at least 1 hour.
Whisk together the flour and cornstarch in a bowl and coat each of the chicken wings.
Heat the frying oil to 300 F.
Carefully place chicken wings in to fry for 5 minutes without over crowding them.
Place all of the fried chicken wings on a cooling rack while heating the frying oil to 350 F.
Fry the wings a second time for 2 minutes to make them extra crispy, then set aside on a cooling rack.
In a large saucepan or a wok, add 1 tablespoon of the frying oil and stir fry the shallots, garlic, red chili, green onion, green bell peppers, and red bell peppers for about 2 minutes on medium heat.
Add the chicken wings to the stir fry and cook for 1 minute.
Season with garlic salt and white pepper, then serve.
