In a small bowl, combine the chicken strips with salt, Shaoxing wine, cornstarch, and white pepper. Mix well to coat the chicken evenly, then set it aside to marinate for 10–15 minutes while preparing the other ingredients.
In a separate small bowl, whisk together soy sauce, oyster sauce, sesame oil, and a pinch of sugar (or other sauce ingredients you prefer). Set the sauce aside for later use.
Heat 1 tablespoon of oil in a wok or large skillet over high heat until shimmering. Add the marinated chicken and stir-fry for 2–3 minutes until golden brown and cooked through. Remove the chicken from the wok and set it aside on a plate.
Add another tablespoon of oil to the wok and toss in the julienned carrots. Stir-fry for 15 seconds before adding the green onions, garlic, chili pepper (if using), baby broad beans, and sweet corn. Stir-fry everything over high heat for 1–2 minutes, allowing the vegetables to retain a slight crunch. Push the vegetables to the edges of the wok to make room for the eggs.
Pour the remaining tablespoon of oil into the center of the wok. Add the beaten eggs and let them cook for a few seconds until they start to set. Scramble the eggs gently with a spatula and mix them with the vegetables.
Add the cold, day-old rice to the wok, breaking apart any clumps with the back of a spatula. Stir everything thoroughly to ensure the rice heats evenly. Return the cooked chicken to the wok and pour the prepared sauce over the mixture. Toss all the ingredients together until the sauce coats the rice and chicken completely.
Continue stir-frying for another 2–3 minutes, allowing the flavors to meld. Once everything is well mixed and heated through, transfer the stir-fry to a serving dish. Garnish with additional green onions or chili slices if desired. Serve hot and enjoy!
