In a large skillet or wok, add cooking oil, sugar, and dried red chili pepper (optional). Let the sugar melt, and then add pork belly.
Brown the pork, making sure both sides are lightly browned.
Add garlic and chili bean sauce, and stir together.
Now, transfer to a clay pot or medium sized pot. On low heat, add michiu, soy sauce, dark soy sauce, and water.
Cover and simmer for an hour, stirring occasionally.
Remove from heat and serve!
