6. Add oyster sauce, soy sauce, salt, chicken essence, sugar and cooking wine, scrub well with your hands, cover with plastic wrap and refrigerate for more than 3 hours.

7. Line a baking tray with tinfoil and preheat the oven to 220 degrees Celsius, top and bottom.

8. Place the baking sheet in the preheated oven and bake for 20 minutes.

9. Turn the ribs over, brush with the marinade for the ribs, brush and place back in the oven for another 20 minutes.
