As for the evaluation, it can be said that large-scale and well-known hospitals generally make people feel that the evaluation will be poor, because these hospitals have far more outpatient visits each year than other hospitals. For example, 1% of outpatients in large hospitals are dissatisfied, that is, 1 10,000 people are dissatisfied, while 5% of outpatients in other hospitals are dissatisfied. It is not excluded that doctors in big hospitals have bad medical ethics, but you should also understand that doctors in these big hospitals are graduates of regular famous universities, and their overall quality is irrelevant.
