At the 4th China International Import Expo, 4746 college students from 40 universities and colleges in Shanghai participated in volunteer work. They have a common name-"Xiaoyezi".

  Li Zhen, a 24-year-old student at the Shanghai University of International Business and Economics, is one of them. This is the fourth time she has participated in the CIIE.

  Li Zhen said that the CIIE is already the place she is most familiar with.

Every year, she and the other "little leaves" will make an appointment to see you next year, which is also her unchanging agreement with Jinbo.
