A villager drives a tractor to plough a field in Yaomo Village of Pengbao Town in Yuanzhou District of Guyuan City, northwest China's Ningxia Hui Autonomous Region, Aug. 27, 2018. In recent years, Guyuan government has strived to develop the cultivation of cool-climate-adapted vegetables through a mechanism that combines planting bases, cooperatives and farmers together. In 2017, the annual per capita income of Yaomo Village reached 13,500 RMB yuan (about 1,985 U.S. dollars), over 80 percent of which came from cool-climate-adapted vegetable cultivation.
