1. Budget: First, determine your budget range. Generally speaking, you can decide according to your gratitude to them and your own financial situation.
2. Preferences and needs: Consider their personal preferences and needs. For example, if they like reading, you can send a book that they might like. If they like music, you can send them a music CD. You can also consider their work needs, such as sending some office supplies.
3. Souvenirs: You can also consider sending some memorable items, such as some souvenirs from your school, or souvenirs related to things they helped you.
4. Price: The price of the gift is not the most important, what matters is your mind. If you can afford it economically, you can consider choosing a gift with a value between 100-300 yuan.
No matter what kind of gift you choose, it is very important to attach a thank-you card to express your gratitude to them.
