What is the difference between a doctor and a doctor?

Doctor originally means doctor, but in foreign countries, such as the United States and Britain, their doctors must obtain a doctorate, so doctor has the meaning of doctor again. So if you are a doctor, a doctor, you can translate it into a doctor or a doctor, because that doctor must have got a doctorate. And if the other person is not a doctor, but a doctor in other industries, then you can only translate into a doctor. Therefore, it is absolutely correct for a doctor to translate into a doctor, and then we can only see whether he can translate into a doctor according to whether he practices medicine or not.
