Place the garlic, ginger, rice wine, soy sauce, salt, Chinese five-spice powder and sugar in a bowl and mix to form a paste. Add the ribs and toss them in the marinade with your hands until they are well coated. Cover and leave to marinate for 1 hour or up to overnight in the refrigerator.
Heat the groundnut oil in a wok over a high heat until the oil starts to shimmer. Add the ribs and stir-fry for 4–5 minutes until browned. Pour in the water, cover and simmer gently for 40–45 minutes, until deliciously golden and tender. Garnish with shredded spring onion.
