Wash hands thoroughly after handling raw spare ribs to avoid cross-contamination; raw meat carries bacteria, and touching other ingredients without washing hands can cause contamination.
Place the spare ribs and pork bone in cold water, add scallion, ginger, and rice wine, boil over medium heat until blood foam appears, then remove and rinse thoroughly.

Spare ribs must be placed in cold water, otherwise blood will be locked in the meat, and the soup will have a fishy smell.
