If you are a student and you really don't have much money, then if you want to give a gift to your father, I think you should give him health. When my father had his birthday, I gave him a filter cigarette holder. Because my father is addicted to smoking and has never been able to quit, as a child, I can only help him minimize the harm. The key is that after my father used the cigarette holder, he saw the tar inside and realized the harm of smoking. Now his smoking has been greatly reduced. I don't know if your father smokes. If he does, this is a good choice.
Other options include men's perfume, but it is relatively expensive. You can also give your father a pen. Or you can customize a cup or T-shirt with a photo of you and your father printed on it, which are all good choices.
Finally, a good report card may be your father's favorite gift now.
