A village in China's Hebei province has taken the country's obsession with QR (quick response) codes to new heights. Officials in Baoding city's Xilinshui village created a scannable code using about 130,000 Chinese juniper trees. It measures 227m along each side, reported Xinhua news agency. The evergreen trees are all between 80cm and 2.5m tall. Whoever manages to scan the code - or an aerial image of it - it will be connected to the village's tourism account on WeChat, a Chinese social media site. QR codes - machine-readable patterns of black squares on a white background - are ubiquitous in China. They are used in settling bills at restaurants, renting out shared bicycles, and even giving money to beggars.
