It is easy for college students to earn money by doing part-time jobs, because many college students' families are not very rich, and even some students' family conditions are very difficult, so these students need to earn living expenses by doing part-time jobs to reduce the economic burden on their families and improve their living standards. Although there are grants and student loans in universities now, there is no guarantee that these grants and student loans will reach every poor student. So there are still many college students who need to work part-time to make money. Another situation is that some college students, although their family situation is not difficult, spend a lot at school, which is beyond the range of living expenses that can be given at home. For example, falling in love in college should be a very common situation. When you fall in love, your daily expenses are high. Usually you can watch a movie, have a meal, go to the playground for a day, and then send a bag, clothes and shoes. These all cost money, which is beyond what your family can give. There is no other way but to make money part-time. Even some college students go directly to rent a house outside, so the rent is an expense. Of course, there are also some students who want to start a business and decide what to do during school, but starting a business requires start-up capital, so they will also make money part-time. Another situation is to accumulate social experience. There are still many college students whose family conditions are very rich, and the living expenses given by their families are completely enough. These students go off-campus to work part-time not to earn living expenses, but to increase their knowledge, get in touch with society in advance and accumulate some social experience. Students generally study on campus, and the school is full of students. The whole atmosphere is completely different from society. The best way to get in touch with the society and get to know it in advance is to find some part-time jobs, so that you can not only accumulate social experience, but also accumulate work experience.
