1. Prepare the ingredients, soak the dried kelp in clean water, blanch the pork short ribs, and rinse well
2. Cut the soaked kelp into thin strips, tie them into kelp knots, and soak the soybeans at the same time. Generally 3 hours in summer and 5-8 hours in winter. The yam is cut into pieces and soaked in salt water to prevent the surface from oxidation and blackening
3. Put the pork ribs and soybeans in a soup pot, add an appropriate amount of water, and bring to a boil over high heat. Then add the kelp knot, cook for 1 hour on low heat, then add yam and wolfberry, continue to cook for an hour, then add salt to season off
