01 - In a mixing bowl, combine the sliced chicken breast with soy sauce, Shaoxing wine, cornstarch, and sesame oil. Toss thoroughly to coat evenly and let rest for 10–15 minutes.
02 - Whisk together the soy sauce, oyster sauce, chili bean paste, rice vinegar, hoisin sauce, sugar, and water in a small bowl until smooth. Set aside.
03 - Heat 1 tbsp of vegetable oil in a wok or large skillet over high heat. Add the marinated chicken in a single layer and stir-fry for 3–4 minutes until golden and just cooked through. Transfer to a plate and set aside.
04 - Add the remaining 1 tbsp of oil to the wok. Toss in the minced garlic and ginger, stirring for 15 seconds until fragrant. Add the broccoli florets, sliced bell peppers, carrot, and halved baby corn. Stir-fry for 3–5 minutes until the vegetables are crisp-tender.
05 - Return the cooked chicken to the wok. Pour in the prepared sauce and toss everything together over high heat for 2–3 minutes until the sauce thickens, coats all ingredients evenly, and develops a glossy finish.
06 - Stir in the sliced spring onions, adjust seasoning to taste, and serve immediately alongside steamed rice.
