Chongqing - We went on a small tour of the exhibition in the central hall during the 2019 Smart China Expo to have a closer look at robots and the future smart technologies. This year's Smart China Expo expects to attract as many as 750,000 visitors, up from 500,000 who visited last year, when the expo was held for the first time. The size and scale of many of the pavilions at the expo this year has been great, and as we round up the third day of the expo, visitors are still flocking to the Yuelai International Expo center, to have a look for themselves. In the central hall, you'll find robots building cars, robots playing with Chinese fans, robots playing piano, and much more. Don't let the hot summer weather hold you back; there is still one more day left!
