01 - Combine chicken pieces with soy sauce, rice wine, egg white, and cornstarch in a bowl. Mix thoroughly to coat and let marinate for 15 minutes.
02 - Heat vegetable oil in a deep pan or wok to 350°F.
03 - Dredge marinated chicken pieces in the additional cornstarch until well coated on all sides.
04 - Deep-fry chicken in batches until golden and crispy, approximately 4-5 minutes per batch. Remove and drain on paper towels.
05 - Discard most of the oil, leaving 1 tablespoon in the pan. Add garlic, ginger, and chili; sauté until fragrant, about 30 seconds.
06 - Mix together orange juice, soy sauce, sugar, rice vinegar, hoisin sauce, and orange zest in a bowl. Pour into the pan and bring to a simmer.
07 - Stir in the cornstarch slurry and cook until the sauce thickens, 1-2 minutes.
08 - Add fried chicken to the sauce, tossing to coat evenly. Serve hot, garnished with green onions and sesame seeds.
