Nestled in a mountainous area, Abuluoha Village is connected to the outside world by only a rugged trail built along a cliff. A one-way trip needs about four hours on foot, while goods are often carried by horses. /VCG Photo

To improve transportation here, local authorities decided to build a 3.8-km-long road connecting the village with Weimu Village of Laguo Township. /VCG Photo

The helicopter helps transport machinery and equipment needed for road construction. /VCG Photo
