Finely mince raw shrimp until they are almost the consistency of a paste. Mix shrimp in a large bowl with ground pork, garlic, ginger, scallions, soy sauce, Shaoxing rice wine, sesame oil, sugar, salt, and pepper.
Use your finger or a pastry brush to dampen the top and right edges of the wrapper with water. Fold the bottom left corner over the filling to meet the top right corner, forming a triangle. Press around the filling to remove any trapped air from the folded wonton.
