Large numbers of migratory birds, including wild geese, grey geese and demoiselle cranes ,have flown to northwest China's Xinjiang Uygur Autonomous Region to enjoy its favorable environment. On the Xinjiang Production and Construction Corps' Hongshan Farm, around 4,900 hectares of spring wheat are swaying in the cool autumn air, waiting to be harvested. The birds flew above the golden wheat fields, forming a picturesque autumn spectacle.
