In Yinchuan, the capital of northwest China's Ningxia Hui Autonomous Region, since June there have been installed many fruit and vegetable vending machines. Yinchuan is one of China's pilot "smart cities," trying to effectively apply technologies in city administration, public security, transportation, health care and environmental protection for better services. "The self-help vending machines can dispense more than 50 varieties of fruits and vegetables, and our staff will replenish the shelves once every two days to make sure the products are fresh," said Chen Yujie, initiator of the concept.
