At present, highland barley, wheat and other crops have gradually matured in the farmland along the river valleys of the Tibet Autonomous Region. The wheat waves in the fields as the breeze blows. In the fields of Tsalna Township, Chushur County, Lhasa, harvesters rumble back and forth, while farmers are busy harvesting the fallen wheat, picking up wheat stacks on the ground and transferring wheat grains threshed by machines.
