Steps
1. Cut the pork belly into 2-inch cubes and blanch in boiling water for 3 minutes to remove impurities.
2. In a pot, heat a little oil and add the sugar, stirring until it caramelizes.
3. Add the pork belly to the pot and stir-fry until browned on all sides.
4. Pour in the soy sauce and Shaoxing wine, and add the ginger, green onion, star anise, and water.
5. Bring to a boil, then reduce heat to low, cover, and simmer for 45 minutes, checking occasionally.
6. After 45 minutes, uncover and let the sauce reduce until thickened, about 10 minutes.
7. Serve hot over steamed rice, garnished with chopped green onions if desired.
