Preheat your oven to 300 degrees Fahrenheit. Once your oven is ready, place your pork jowls into a braising pan and add water until the pork is halfway submerged.
Add your soy sauce, fish sauce, rice wine, sugar, garlic, chili, 1 stick of cinnamon, and salt and pepper to the water. Bring the pan to the boil on the stove and reduce it to a simmer.
