You should still be a student, so your gift doesn't need to be luxury goods. You should choose a gift according to your ability. In fact, gifts are just to convey your thoughts, to express gratitude or love to others. The person you want to give a gift to is your cram school teacher, who should be someone you respect. Here are my suggestions:
1. You should consider the age of your teacher. If he is older, you can consider buying some tea or small health care equipment. People of this age should pay attention to health. If he is a young teacher, you can consider giving him a notebook, a pen or other meaningful gifts, so that he will like it.
2. You can consider giving something creative. I gave my teacher a real doll before, which was made based on a real person. It was very good. The teacher liked it very much. When I went to his house, I saw him put it in the most conspicuous place in the house.
3. Give the teacher desk decorations: such as desk calendars, water cups, digital photo frames, handicraft pen holders, handicraft decorations, etc.
