The promotional theme song for the 2019 World Internet of Things Expo was released on Sept 4, three days ahead of the event.

Composed and sung by Wuxi musician Du Yichao, the song touches on such concepts as a digitalized new economy, intelligent manufacturing and data technology.

In the music video, Du dresses up as a fisherman and sings the song in Yixing Bamboo Sea Scenic Area, Xihui Park, Nanchang Street and other famous tourist attractions in Wuxi.

The work is a harmonious blend of old and new.
