01 - Combine chicken slices with soy sauce, Shaoxing wine, and cornstarch in a bowl. Mix thoroughly to coat and let stand for 10 minutes.
02 - Whisk together hoisin sauce, soy sauce, rice vinegar, sugar, sesame oil, and water in a small bowl until well combined. Set aside.
03 - Heat 1 tablespoon vegetable oil in a large wok or skillet over high heat. Add marinated chicken and stir-fry until just cooked through, approximately 3–4 minutes. Remove chicken from wok and set aside.
04 - Add remaining oil to the wok. Add garlic and ginger, stir-frying for 30 seconds until fragrant.
05 - Add bell pepper and carrot to the wok. Stir-fry for 2–3 minutes until vegetables are slightly tender but still crisp.
06 - Return chicken to the wok along with scallions and bean sprouts. Stir-fry for 1 minute to incorporate.
07 - Pour prepared sauce over the stir-fry mixture. Toss well to coat all ingredients evenly. Continue cooking for 2 minutes until heated through and sauce has slightly thickened.
08 - Transfer to serving plates and serve immediately. Garnish with additional scallions if desired. Accompany with steamed jasmine rice or thin pancakes.
