1. Soak in water first, remove blood
2. Winter melon, yam cut
3. After the soaking is complete, boil the ribs in boiling water. After boiling, remove the foam, about 5 minutes, remove the ribs and rinse in cold water
4. Add all the ingredients, and the salt is ready to cook in the end. I made it with a rice cooker. The rice cooker has a soup-making effect for 2 hours. Don't worry about it.
