The attending doctor is the physician who oversees Fu Yanci after he wakes up. He is the one who says “Third Master Fu can’t drink water or eat yet” when Fu Yanci complains of thirst. He also notes later that “the doctor has done everything possible” and mentions that the IQ dropping to three or four years old is a possibility. He is present during the family discussions about Fu Yanci’s condition and gives practical medical advice. His calm, factual tone contrasts with the family’s emotional distress.
