Cut the chicken thighs into bite-sized pieces.
Place them in a bowl and add soy sauce, Shaoxing wine, sesame oil, egg, and white pepper.
Working in batches, add the marinated chicken pieces to the cornstarch and toss until thoroughly coated.
Heat approximately 2 inches of neutral oil in a heavy-bottomed pot or deep skillet to 350°F (175°C).
Fry for approximately 4–6 minutes, turning occasionally, until golden brown and completely cooked.
Transfer the chicken to a wire rack or paper towel-lined plate.
In a bowl, whisk together soy sauce, hoisin sauce, rice vinegar, brown sugar, honey, chicken broth, and cornstarch.
Stir-fry for approximately 30–45 seconds until fragrant.
Bring it to a gentle simmer, stirring continuously.
Don't cook for too long after adding the chicken, as extended cooking can soften the crispy coating.
Sprinkle with green onions and toasted sesame seeds.
Serve immediately over steamed white rice, fried rice, or noodles with your favorite vegetables.
