Horticultural exhibits delve into high-tech magic

The ongoing International Horticultural Exhibition 2019 in Beijing is all about gardening, but it doesn't shy away from high technology that improves visitors' experience.

To provide visitors with information services, ticket purchasing, parking, travel routes, introductions to scenic spots, medical services, performance arrangements and traveling tips, a mobile phone app called Expo 2019 was developed.

It's like having a tour guide at hand, said Guo Ziliang, an official at the Beijing World Horticultural Expo Coordination Bureau, the expo's organizer.
