In a bowl, combine the hoisin sauce, soy sauce, oyster sauce, honey, Chinese five-spice powder, minced garlic, and grated ginger to make the marinade.
Add the sliced pork to the marinade, ensuring each piece is well coated. Cover and refrigerate for at least 30 minutes to marinate.
Preheat the grill to medium-high heat.
Thread the marinated pork slices onto the soaked bamboo skewers.
Brush the grill grates with vegetable oil to prevent sticking.
Grill the pork skewers for about 2-3 minutes on each side, basting with any remaining marinade, until cooked through and slightly charred.
Serve the Char Siu Pork Skewers with steamed rice and your favorite grilled vegetables.
Enjoy the flavorful and tender grilled pork skewers!
