This is an introduction video I made for RUC (Renmin University of China) Summer School Program in the year 2009. I also made videos for the summer school in the year 2010 and 2011. Last year, staffs from educational administration of RUC went to Europe with my video to promote the Summer School Program. It is a good way for the global students to know more about RUC Summer School and participate in the Program. Making contribution for my university is my pleasure. At the same time, I would like to see my work go abroad and show to the international audiences.
