Wash and clean the chicken bones and pork ribs. Blanch them.
Put all the ingredients except the cabbage in to boil.
Once the soup boils, add in the cabbage.
Once it boils again, simmer on low heat for 2-3 hours. All the taste of the cabbage would be out in the soup by then. This is purely for stock purposes so if you are making this soup for adults, you will only put in the cabbage about an hour or so before serving so that the cabbage isn't totally tasteless!
Strain the stock and pack into suitable portions after it cools.
