"Stop arguing, both of you," said the nurse as she hurried to intervene between two quarreling relatives of patients. "The doctor is here."
Zhang Wei's mother gasped for breath, caressing her chest, deeply irritated by the son of the patient in the next bed. Turning around and seeing that the doctor by the bedside was Xie Wanying, she panicked and rushed over, yelling, "Didn't I ask for a doctor? What can a student do?"
"It's Doctor Sun's instruction for Dr. Xie to come check on the patient," the nurse explained.
Zhang Wei's mother couldn't believe it and asked Xie Wanying, "What's your relationship with Doctor Sun?"
Li Qi'an, who had stood up to follow and see the patient, entered the ward and heard the relative's question. He replied, "Doctor Sun is our teaching physician."
"Other than the teacher-student relationship, there's no other connection? Why does he always send you to see patients instead of coming himself?" Zhang Wei's mother demanded.
