To prepare the pork, use a fork to pierce all over the pork butt. This helps the marinade absorb faster and speeds up the cooking process.
To marinate the pork, in a bowl, mix together the fermented red bean curd, fermented red bean curd sauce, oyster sauce, hoisin sauce, soy sauce, dark soy sauce, rice wine, honey, five-spice powder, and white pepper. Add the pork and coat well with the marinade. Let it sit for about 5 minutes.
To sear the pork, in a pan over medium heat, add the cooking oil. Add the pork and sear for about 2 minutes on each side until lightly browned.
To braise the pork, add the smashed garlic, remaining marinade, and water. Cover and cook for about 15 minutes, or until the pork reaches an internal temperature of 165°F.
To finish, uncover and increase the heat to high. Reduce the sauce for about 3 minutes, spooning the sauce over the pork frequently as it thickens. Slice the pork into small pieces and serve hot.
