(1) is conducive to promoting the socialization of college students. By taking part-time jobs in society, they get more contact with society, experience life in the ups and downs of part-time jobs, and cultivate their personal abilities; Through down-to-earth practice and tempering from success and failure, they can better understand themselves and understand what role they will play after entering the society; Through observation and part-time study, we can examine social norms and requirements, review our own problems, and establish learning goals that meet social requirements.

(2) It is beneficial to strengthen students' professional concept and correct learning attitude. Through part-time jobs, they find that the social competition is fierce and cruel, and it is not as easy to survive in the society as expected, so as to change themselves, consciously standardize their lifestyle and behavior, take their work seriously, innovate constantly, and gradually form their own professional ideas. More importantly, after such an experience, they will feel that the opportunity to study in college is rare, so they cherish their college time more and study hard.

(3) It is beneficial for college students to integrate theory with practice and improve their comprehensive quality. Through part-time jobs, college students, on the one hand, apply the book knowledge they learned in school to practice, deepen their understanding of theory, or deepen their professional knowledge when studying and solving problems that are not involved in books. On the other hand, the social part-time job goes out of the original life circle and comes into contact with a lot of non-book knowledge, such as interpersonal relationship and adaptability, so as to learn a lot of things that schools can't learn, expand the knowledge of college students, cultivate their abilities and improve their comprehensive quality.
