Preheat broiler.
In a medium mixing bowl, combine the pork, ginger and minced green onion, stirring in one direction.
Add egg and breadcrumbs and keep stirring in one direction.
Add soy sauce, ShaoHsing wine, oyster sauce, white pepper and cornstarch. Stir in one direction until the texture is sticky and comes together. Add 2 tablespoons water and stir until the mixture becomes soft and pasty. If needed, stir in another 2 tablespoons water.
Evenly divide the mixture into eight portions and shape into meatballs. Place the meatballs on a sheet pan lined with foil.
Place the meatballs under the broiler for 7-10 minutes until browned.
Meanwhile, in a wok or dutch oven on medium heat, add oil and rock sugar. Cook until the sugar is melted and caramelized. Add ginger and green onion pieces and stir fry for 30 seconds.
Pour in chicken broth and add ShaoHsing wine, soy sauce, dark soy sauce, and oyster sauce. Bring to a boil.
Gently place the meatballs. Turn the heat down to a low simmer. Cover and braise for 1 hour, flipping them once halfway through cooking.
Fill a medium pot with water. Add 2 teaspoons salt and 1 tablespoon oil to a medium pot of water. Bring it to a boil on high heat.
Once the water is boiling, add vegetables. Cook for 30 seconds.
Drain the vegetables and arrange them on a serving plate with a lip.
Gently place the meatballs on top of the vegetables. Spoon the sauce over the meatballs and garnish with remaining green onions.
