First, for College Students' Day, you can choose creative gifts that can be engraved, and use gifts to express your blessings to your girlfriend. Here I recommend you a heart-shaped chocolate gift box that can be engraved, and you can customize it with "Happy Holidays" to give your girlfriend a sweet and romantic holiday surprise!
Second, College Students' Day is right, but for boyfriends and girlfriends, you can celebrate it as Valentine's Day. For example, girls like plush toys, so you can carefully choose a cute doll for your girlfriend on College Students' Day. It is recommended to choose this kind of glowing teddy bear, which will make you feel safe when you are with your girlfriend at night.
Third, as far as I know, girls have a special liking for fantasy music boxes. It is a good idea to give your girlfriend a music box on College Students' Day, especially some creative music boxes that can be customized. Whether it can be printed with photos or engraved, it is quite commemorative.
