Patient : Doctor, doctor! Come and see, why do you think I always have a chest pain after the operation? (fell very aggrieved as well as anxious)Doctor Chen: Don’t shout! Your chest has a wound, how can it not hurt?Patient: The patient in bed 5 has had the same operation as me on the same day. I can’t understand why he doesn't have pain. I guess there's something wrong with the operation operated by you? (showing dissatisfaction)Doctor Chen: It must be ok if I say it’s OK. I am a doctor but are you a doctor? Patient: I think there's something wrong with your operation. Wait, I'm going to the medical department to sue you! (very angry)What kind of communication does this case belong to
