Cut the pork belly into bite-sized pieces
Blanch in boiling water for 2-3 minutes to remove excess blood and impurities

Add the rock sugar and a splash of oil or water
Stir gently until the sugar melts and turns into a golden brown caramel
Add the pork belly into the caramelized sugar
Stir-fry until the pork is evenly coated
Add light soy sauce, dark soy sauce, and cooking wine. Stir well
Add ginger slices, scallion segments, star anise, and cinnamon
Pour in enough hot water to just cover the pork
