I think it is more appropriate for college students to set up stalls in their spare time, but they should be well balanced. Many college students will also do some part-time jobs during the summer vacation or in some spare time, but they just can't balance the relationship between study and part-time, which may not be exquisite and their academic performance is not good. So I think college students must find out what they want before setting up a stall. If you think that setting up a stall will affect your time and energy and make you unable to devote yourself to your study, then you'd better not set up a stall. So I think that when we college students do something now, we always think of ourselves as college students and regard the university as our umbrella. But without the umbrella of the university, we can't do many things. It's good to have this idea, which shows that you want to be independent. Most of us are adults in college, but many students live on the living expenses at home. In fact, I think I can do some part-time jobs in my spare time or during the winter and summer vacations, and it is no problem to eat by myself. Many students also love face, so they feel that they can't take this first step. In fact, we all rely on our own labor and our own hands to eat. There is nothing to be ashamed of. Others will think that you do this, and may envy you and think that your ideas are novel. I think it can be a big income for college students to set up stalls in their spare time. Because I think this income corresponds to college students, who have money and can decide what to buy by themselves. I think if you are a primary school student, it is no problem to attract them with your things, but they may have no money or their parents may not agree to let them buy them. If you choose to set up a stall at this stage, you can also adapt to life after entering the society in advance, because I think these are all the same.
