Zhang Yongfu and Pan Pan are both excellent talents, but their specialties and achievements may be different, so we can't simply compare them. Zhang Yongfu, a professor in Tsinghua University, has rich teaching and scientific research experience and has published many important papers and speeches. His research achievements in the field of computer science and technology are outstanding, and he has won the ACM SIGGRAPH Award for Outstanding Achievement in Computer Graphics, IEEE Fellow and other honors. On the other hand, Pan Pan is a successful business leader. I used to work in a private equity company in the United States, and now I am an important manager of some large enterprises. His research achievements in the field of robotics are also outstanding, and he has won honors such as the National Science Fund for Outstanding Young Scholars and the Second Prize of National Natural Science. Therefore, we can't simply compare them. We need to choose tutors to study and cooperate according to specific fields and personal needs.
