I think it is a good behavior for college students to earn their own living expenses. This can not only help them reduce the financial burden of their families, but also cultivate their independence and self-management ability. Through their own efforts to earn living expenses, college students can better understand the value and importance of money, so as to cherish the fruits of their labor. In addition, it is also an opportunity to exercise their abilities and increase their social experience, which will help them better adapt to society.
