Wash the chicken, cut it into pieces, put it in a pot, add water and ginger slices, boil it until it boils, and take it out for later use.
Put the chicken pieces in a stew pot, add ginger slices, onion slices and cooking wine.
Add enough water to the stew, cover it and simmer for 2-3 hours.
Stew until the chicken is cooked and the soup is rich, and add some salt to taste.
