Mix 1/2 teaspoon of sugar with the shrimp, mix, and add shrimp to a cold wok.
Cook at medium heat until pink and done. Remove the shrimp to a mixing bowl.
Add 1 tablespoon of oil to the pan and add the ground pork. Break apart and cook until the pork is no longer pink. Add to the shrimp.
Heat 1 tablespoon of oil in the wok and add the scallion whites, black beans, ginger, garlic, 1 tablespoon of hoisin, and 1 teaspoon of sugar. Cook over low heat, stirring constantly, for about 1 minute.
Turn off the heat, and add the shrimp, ground pork, scallion greens, soy sauce, and sesame oil and toss to coat.
Transfer shrimp to a platter and serve.
