It is said that pig trotters can promote milk production, how to make them?

Patient's question:

No

Doctor's answer:

Pour cold water into the pot, add the pork knuckle pieces, and heat over high heat until the water boils. Boil for about 10 minutes until the blood foam completely subsides, then remove and drain.
In a clean pot, add rock sugar and a small amount of water, heat over low heat. Once the sugar melts into a golden syrup, pour in the pork knuckles and stir evenly to coat them with the caramel color.
Add peanuts, scallion sections, ginger slices, garlic cloves, soy sauce, and cooking wine to the pot with the pork. Pour in an appropriate amount of warm water, cover the pot, and bring to a boil over high heat. Then reduce the heat and simmer for 1 hour. Open the lid, stir the pork knuckle pieces, and then cover the pot again to simmer for another 20 minutes until the broth thickens and the pork turns a bright red.
