Who is the patient?

Biming's medical examiner friend was treating Caishen like a patient. She examined his hands, legs, tongue, heart beat and asked him questions. 

"Have you been experiencing shortness of breath?" 

Caishen shook his head. 

"Headaches?" she asked. 

He nodded. 

"How often?" she went on to inquire. 

"Once or twice daily." Biming answered on Caishen's behalf. 

"Do you have one now?" she asked. 

He shook his head, ever since he carried the cat, all traces of the headache had disappeared. In fact, every time he had the cat in his arms, the headaches, fatigue, weakness, it would all vanish. 

"Any coughing?" she asked. 

"No," Again, Biming answered. 

"Fatigue, weakness or drowsiness, have you experienced anything like that?" 

She has a paper on which she was ticking things or noting down. It was almost like a real doctors interview except for the fact that they were in his office. 

"Nausea or vomiting?"
