The emergency department is busy; sometimes several patients come in at once, and a single ER doctor can definitely become overwhelmed, missed details are inevitable. It has been statistically proven abroad that the most common medical errors are missed and misdiagnosed cases, and they can't always be completely avoided.
This was something that neither Doctor Jiang nor Huang Zhilei could refute. Doctor Jiang had no choice but to tell the truth, "The problem is, it wouldn't be appropriate for me to make suggestions. Since I'm neither a thoracic nor a cardiology doctor, I'm not a specialist in this area, and I don't have persuasive power."
If you're going to argue with someone, without bringing in an expert in that field, they won't pay any attention to you at all.
Because you're not a specialist in that field, what right do you have to argue with a specialist about their expertise?
