In clinical practice, some patients dislike certain young doctors because, as Teacher Tan said, these doctors are unsure of their diagnosis and can only widely cast a net. If patients compare them to more capable doctors, they will think these doctors only order tests and nothing else, and certainly refuse to let you waste my money on tests. Don't assume just because I have money, you can easily fool me like this. This is the mentality of patients like Mother Yaxi.
Being responsible to the patient isn't about ordering a bunch of tests for no reason, creating psychological pressure without evidence. You, as a doctor, believe I, the patient, have some issue, please make it clear, don't be ambiguous and talk about your gut feelings. When patients seek you out, they're looking for science, not for you to perform tricks and order tests based on feelings.
