Clean the pork thoroughly and prepare it.
In a pot, add the pork, green onion, garlic, ginger, pepper, and water, then bring to a boil.
Remove any foam that forms while boiling.
When the pork is cooked, take it out and slice it into bite-sized pieces.
Bring the pork broth to a boil again and season with salt.
Place the sliced pork and broth in a bowl, garnish with chopped green onion and pepper.
