The holding of G20 summit in Hangzhou was a rare opportunity for Hangzhou to improve internationalization level, transformation, updating and city image. It was also a good opportunity for college students to expand international view, promote national spirit and exhibit their styles. Various schools of our university acted positively to organize students to participate in the activity. After trainings on skills and etiquettes, they were designated to posts of banquet hall services, tea arts and etiquette services.
