In the afternoon of November 30th, the first “Drink Hour” Academic Salon was held at Room 610, Weiqing Building. Prof. Li Changsheng was invited to make a face-to-face communication with other faculties and students. The Salon was well received and there were nearly forty students and faculties attended. “Drink Hour” provides a free discussion platform for all the students and faculties in CESS and it will play an important role in constructing relaxing academic atmosphere in our center.
