As long as you are doing well in college now, opening a Taobao shop to earn some living expenses can't be considered as not studying hard. It only shows that you can open a shop to make money without affecting your studies, which shows that you are very capable. I just think that opening a Taobao shop should be asked a lot of questions by the interviewer, and each HR may have different concerns and ask different questions when opening a Taobao shop. The most important thing is whether your experience in opening this Taobao shop may add points to the position you are applying for. If it is dispensable, it is better to be conservative and not write!
