The two instructors have their own merits. Instructor Zhu Cimian focuses on the structural direction, while instructor Liu Chunyuan focuses on the geotechnical direction. They are first-level structural engineers and registered geotechnical engineers respectively. I heard that Mr. Liu Chunyuan passed the exam in one go. He is very rigorous and good in the field of academic research, and he seems to be a professor at an engineering university in the United States. But in terms of reputation, Mr. Zhu from Tongji is very good. Most civil engineering students should have heard of the structural mechanics textbook he edited. I have also read the book he edited, although the school uses the Tsinghua version of Long Yuqiu. Anyway, each has its own merits! !
