2. Shortcomings are lack of experience and knowledge, limited funds and lack of professional skills. The disadvantage of college students' starting a business is that they may lack practical experience and professional knowledge compared with those who have started a business for a while, and they need to make up for it through study and practice. College students often face the problem of shortage of funds, and it is difficult to support a complete entrepreneurial project. They may need to find investment, get financial support or rely on personal savings. In some industries, especially those related to technology or science, college students may lack the support of professional skills and need further training or recruiting experienced team members.
