Since the expo was first held in 2015, more than 2,900 young people have been selected as volunteers to provide translations, help arrange meetings, offer guidance, consultations and other services. They have reportedly received overwhelmingly positive evaluations from the expo executive committee, guests and visitors.

The 2021 Big Data Expo is being held in Guiyang on May 26-28. The online version of the event started on May 20.

Prior to the expo's opening, volunteers have rehearsals at Guiyang's airport and train stations on how to meet and pick up guests. [Photo provided by executive committee of Big Data Expo]
