China's Xiongan New Area is rolling out an urban management system powered by AI, big data and cloud computing. Dubbed the "city of the future," Xiongan sits about 100 kilometers southwest of Beijing and was established in 2017. Its all-in-one platform keeps the place ticking over with streets cleaned, neighborhoods safe and recycling sorted. The care reaches into every household. With data monitored around-the-clock, the platform flags anything unusual instantly.
