Villagers from Hongsipu District of Wuzhong City, Ningxia Hui Autonomous Region, plant trees beside a local highway. Recently, the local governments of Ningxia's cities and counties have launched a campaign to plant trees in a bid to improve the regional environment. Ningxia boasts a higher survival rate of saplings in early winter due to the low temperatures, high humidity and small amount of evaporation during the period. [Photo: Xinhua]
