The physician is a doctor in the town whom Han Mingyuan once begged for help when his fourth brother was feverish as a child. Han Mingyuan kowtowed until his forehead bled before the physician agreed to treat the boy. Later, Han Mingyuan worked at his shop for over a month to pay for the medicine. This physician is a past figure who appears in Han Mingyuan’s memory, demonstrating the brother’s former kindness and the ungratefulness of his family.
