01 - In a mixing bowl, combine the thinly sliced chicken breast with 1 tbsp soy sauce, Shaoxing wine, cornstarch, and sesame oil. Toss thoroughly to coat evenly and let rest for 10 to 15 minutes at room temperature.
02 - In a small bowl, whisk together 2 tbsp soy sauce, oyster sauce, chili bean paste, rice vinegar, hoisin sauce, sugar, and water until smooth and well combined. Set aside.
03 - Heat 1 tbsp vegetable oil in a wok or large skillet over high heat until the oil just begins to shimmer. Add the marinated chicken in a single layer and stir-fry for 3 to 4 minutes until golden and cooked through. Transfer to a plate and set aside.
04 - Add the remaining 1 tbsp vegetable oil to the same wok over high heat. Add minced garlic and ginger, stir-frying for 30 seconds until fragrant. Toss in the broccoli florets, sliced bell peppers, carrot, and halved baby corn. Stir-fry for 3 to 5 minutes until the vegetables are crisp-tender.
05 - Return the cooked chicken to the wok. Pour the prepared sauce over the chicken and vegetables, tossing continuously for 2 to 3 minutes until everything is evenly coated and the sauce becomes glossy and thickened.
06 - Stir in the sliced spring onions and adjust seasoning to taste. Transfer to a warm serving dish and serve immediately alongside steamed rice.
