In China, QR codes are insanely popular and are used by everyone, from big retailers to buskers, for a variety of purposes, from sharing information to making payment.
The Xilinshui village in Hebei has used 130,000 Chinese juniper trees to create the biggest QR code ever. The code measures 227m (744 ft) along each side and is designed to be scanned by passengers as they fly over on planes travelling to Beijing. The trees range from 80cm to 2.5 metres in height, so that the code can actually be scanned.
After scanning, the code takes you to Xilinshui’s official tourism page on WeChat, China’s biggest messaging app. With all the coverage generated, people may also be able to scan the code from images, so the stunt has an even wider reach than perhaps intended.
