Guiyang, capital of Southwest China's Guizhou province, is also known as a big data city. It is home to the world's most large-scale big data centers and is a demonstration city for the integration of big data, 5G and smart technologies. Josh Arslan, a vlogger from the United Kingdom, visited Guiyang to learn how the city applies big data and 5G in smart transportation, including taking the metro, finding parking spots, and pilotless automobiles.
