At present, the most popular gifts for doctors are pennants, thank-you letters, flowers, fruits, milk and drinks. These are gifts that most male and female doctors are willing to accept. These gifts are more formal and reasonable, so don't be too cautious when sending them as red envelopes. Just take them directly to the doctor's office and send them to the doctor. However, it should also be noted that not all doctors are willing or willing to accept these gifts, so be a little cautious when sending them and ask the opinions of nurses or other patients.
