Marinate the pork ribs with light soy sauce, Shaoxing wine, white pepper, and cornstarch for at least 15 minutes.
Heat vegetable oil in a wok or deep pot to 180°C (350°F). Deep-fry the marinated ribs in batches until golden brown and cooked through, about 5-7 minutes per batch. Remove and drain on a wire rack.
In a small bowl, combine ketchup, Worcestershire sauce, white vinegar, sugar, dark soy sauce, and sesame oil to make the Peking sauce.
Discard most of the oil from the wok, leaving some. Add minced garlic and ginger, stir-fry until fragrant.
Pour in the Peking sauce mixture and bring to a simmer. Add the fried pork ribs, toss to coat evenly with the sauce. Serve immediately.
