01 - In a mixing bowl, combine the sliced chicken breast with 1 tbsp soy sauce, Shaoxing wine, cornstarch, and sesame oil. Toss until evenly coated and let rest for 10 to 15 minutes.
02 - Whisk together 2 tbsp 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 vegetable oil in a wok or large skillet over high heat until the oil just begins to smoke. 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 wok. Toss in the minced garlic and ginger, stirring for 15 seconds until fragrant. Add the broccoli florets, bell peppers, carrot, and baby corn. Stir-fry for 3 to 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 for 2 to 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.
