The correct way to make stewed big bone soup with pig bones is as follows:

Materials/tools: 2 big bones, 2 onions, 1 ginger, 2 spoons of cooking wine, 1 spoon of white vinegar, appropriate amount of salt, knife, pot and plate.

1. Chop the big bone into two parts (which can make the butcher chop it well) and wash it with clear water.

2. Cooking wine, ginger slices, and shallots for later use.

3. Blanch the big bone with cold water to remove the blood powder, and rinse the impurities with cold water repeatedly.

4. Add cold water and big bones to the pot, add the onion, and bring the ginger slices to a boil.

5. Add salt when drinking. You can add your favorite vegetables to the boiled bone soup for better nutrition. You can cook noodles as a dish. Keep the rest as broth and put it in a sealed container for freezing. Take it out when using.
