On the afternoon of March 22, 2013, Dr. Thomas Davis from the University of Northern Iowa visited the Department of Physical Education in the College of Education at Zhejiang University and gave a lecture to faculty and graduate students. The lecture “The Youth Risk Behavior Surveillance System (YRBSS)” aroused the great interest of the audience and lead to many lively discussions. In addition, Dr. Davis also watched a martial arts performance given by students. He gave very high praise for the performance.
