Heat the oil in a wok over high heat. Add the garlic, ginger, and red bell pepper. Stir-fry briefly and add the shrimp. Deglaze the wok with the wine. When the wine is almost evaporated and the shrimp are nearly cooked through, add the salt, black pepper, Szechwan pepper, 5-spice powder, and sugar and stir-fry rapidly, taking care not to burn the spices. Remove from the heat immediately and serve with sesame plum dipping sauce.
