1. Cut the bought pork belly (that is, lean meat and fat meat are layered) into 1 cm square (regardless of thickness, only consider length and width);

2, put oil in the pot (more), add a spoonful of sugar (white sugar is also ok) after heating (more), stir fry until it is paste (there should be smoke in the pot at this time, don't be afraid). Pour chopped meat and seasonings (thick slices of ginger, garlic, cinnamon, dried peppers, star anise and dried tangerine peel (not dried tangerine peel)), stir-fry for three minutes, and then the meat turns dark red;

3. Add a proper amount of salt, a spoonful of soy sauce, 1/5 tablespoons of vinegar, half a spoonful of sugar, two tablespoons of cooking wine, half a spoonful of chicken essence, and clear soup (cold water is also acceptable) until the meat is submerged for 3 mm, and the fire boils (it begins to smell);

4. Pour into a saucepan and simmer for 1.5 hours. At this point, the soup should be small and sticky (if there is too much soup, you can collect the soup on high fire, but you should stand by and watch), add green pepper (not very fat lantern pepper), add some coriander, then taste the salty taste and simmer for 3 minutes.
