Let's prepare the sauce! In a bowl, combine soy sauce, dark soy sauce, sesame oil, Shaoxing wine, sugar, and black pepper powder. Mix together well and set aside.
In a deep pan or wok, heat up 2 tablespoons of oil over medium-high heat. Toss in the onion and cook for 1 minute.
Next, add garlic, long green pepper, and carrot. Cook for 1 to 2 minutes until fragrant. Add the char siu and stir fry everything together.
Toss in the rice and break the rice apart using a spatula or spoon.
Pour the sauce over the rice and mix together until the the rice is evenly coated.
Push the rice to one side of the wok and add the remaining tbsp of oil on the side without the rice.
Crack an egg and gently scramble. Then, mix the egg in with the rice. Taste for seasoning and adjust with salt if needed.
Garnish with scallions and enjoy!
