Self-service vegetables are displayed on Zhangtang Road in Hefei, East China's Anhui province. The booth has no salespeople with price tags stuck to the vegetables. The booth owner Ms Bao said the vegetables are planted by her family and all are pollution-free. Despite low business, she said the stall is not to make money but to save waste. Customers leave their money and nobody has ever stolen from the stall. [Photo/Xinhua]
