Combine the marinade ingredients with the pork and allow to sit for 15 minutes while you prep the other ingredients. Slice the tofu, peppers, and celery.
In the wok, heat 1 tablespoon oil over high heat. Stir-fry the spiced tofu for a couple minutes until browned slightly. Set aside.
Heat another tablespoon of oil and stir fry the peppers for about a minute. Dish out and set aside. Do the same with the celery.
Add another tablespoon of oil to the wok, keeping it over high heat. Stir-fry the marinated pork until brown. Then add in cooked tofu, peppers, and celery. Immediately add salt to taste, 1 teaspoon of sesame oil, 2 tablespoon of Shaoxing wine, white pepper, and a teaspoon of light soy sauce. Stir-fry everything together for another couple minutes until combined. Plate and serve with rice!
