Following the success of bike-sharing schemes in China, sleep-sharing has arrived. Whether you need a 30-minute power nap in the middle of the day or a good night's sleep, visitors can now rent a sleep capsule at a mini-hotel in Zhongguancun, a technology hub for startups in Beijing. When tiredness sets in, people simply scan a QR code on the outside of each capsule and pay 6 yuan per 30 minutes during off-peak times or 10 yuan per half-hour for peak times. [Photo/VCG]
