Rinse the pork bones and soak in cold water for at least 30 minutes (ideally 1-2 hours). If soaking for at least 1 hour, change water out halfway through.
Blanch the cabbage and strain.
Blanch the pork bones in boiling water, then wash each bone.
Cook the bones with ginger, soy bean paste, mushrooms, onion, dried red pepper, and water for 90 minutes.
Make the seasoning paste by combining garlic, hot pepper flakes, hot pepper paste, fish sauce, perilla seeds powder, black pepper, and water.
After 90 minutes, add the cabbage, soybean sprouts, green onions, potatoes, and seasoning paste to the pot.
Cook for 30 to 40 minutes until the potatoes are fully cooked.
Add perilla leaves and stir before serving.
