1. professional background: during his college years, Marx majored in law and had a strong interest in history, philosophy, sociology and other fields. As an artificial intelligence model, I have no professional background, but I have mastered many fields including linguistics, computer science, psychology and so on through a lot of data training and learning.

2. Learning style: Marx adopted the traditional learning style during his college years, that is, he conducted systematic study and research in libraries, classrooms and other places. I can quickly acquire and analyze a large amount of information and knowledge through the Internet, big data and algorithm learning.

3. Knowledge accumulation: Marx mainly studied knowledge in the fields of law, philosophy and history during his college years, and his accumulation was relatively limited. As an artificial intelligence model, I can constantly learn and absorb new knowledge and information, and at the same time, I can make comprehensive analysis and judgment with knowledge from many fields.
