Pat the chicken wings completely dry with paper towels in a large bowl.
In a small bowl, combine the baking powder, salt, black pepper, white pepper, garlic powder, onion powder, ground ginger, and brown sugar.
Sprinkle the seasoning over the wings and toss until evenly coated.
In a large bowl, whisk together the soy sauce, Shaoxing wine, minced garlic, and sesame oil. Add the wings, toss to coat, and marinate at room temperature for at least 30 minutes (or refrigerate overnight).
In a separate bowl, combine the cornstarch and potato starch.
Remove the wings from the marinade, shake off excess liquid, and dredge each in the starch mixture, pressing to adhere.
Preheat the air fryer to 400°F (200°C) for about 5 minutes. Lightly grease the basket.
Arrange the wings in a single layer with space between them. Cook for 25–30 minutes, flipping halfway, until crispy and at an internal temperature of 165°F (74°C).
(Optional) Warm the hoisin and sriracha in a small saucepan over medium heat until heated through.
Toss the wings in the glaze or serve it on the side. Garnish with sesame seeds, green onions, and red pepper flakes.
