Chen Yuhui (Dais Head)：
Hi, every delegate, I'm Yuhui Chen, a sophomore from Faculty of Finance. It is my second year to be in the Dais, and it is really a pleasure to acquaint outstanding delegates every year. The topic this year, AIDS prevention and control, is a long-standing problem exists. Hope you can come up with some great solutions to this problem after several days of preparation and two days of sessions. Good luck to you all!
