Thanksgiving is a Western holiday. During this holiday, you should express your gratitude. Your teacher teaches English, so she should attach great importance to this holiday. You said you can give her a gift on this holiday. She is your teacher, so you should know her better. You should know her preferences more or less. For example, she likes to drink a cup of green tea before each class, so you can give her a box of green tea to please her. Then it depends on whether your teacher is a person with a high level of culture. If she has elegant interests, you can give her some literati calligraphy and paintings. If she prefers material enjoyment, you can give her some food, drinks, and toys. Or, you can also give her something personalized, such as a music box, but you can write your blessings on it. I have made this one online before, and it is very good. Basically everyone likes it very much. You can try it~
