Place pork ribs and water in a soup pot and bring to a boil. Keep removing the scum until the soup is clear.
Once the soup is clear, add angelica root, lovage rhizome, garlic, cinnamon, star anise, and cloves. Season with dark soy sauce, soy sauce, salt, and sugar. Once it boils again, reduce heat, cover the pot with a lid, and simmer for 1 hour, or until the pork is cooked and tender.
Add shiitake, tofu, and wolfberry fruit into the pot. Bring to a boil again, and cook for another 10 minutes. Adjust with salt and sugar as needed.
Turn off heat, and serve hot with the chili and garlic soy sauce accompanied with a bowl of steamed white rice.
