step

1. Wash the bones bought in the supermarket (usually supermarkets will cut them off), soak them in cold water for many times, and pour out the blood before soaking.

2. Until the water becomes clear.

3. Boil, skim off the floating foam on it, and after soaking in clear water for several times, there is basically no floating foam.

4. Simmer 1.5-2 hours and add a little salt to taste.

Add ginger slices later, or the soup will be bitter.
