On January 17th, a large flock of swans danced gracefully between the ice surface and the reeds in the Jiayuguanohu National Wetland Park, with their chirps echoing back and forth, injecting a lively vitality into the winter of the magnificent pass and forming a beautiful ecological picture the Qilian Mountains in the distance. In recent years, as the protection efforts for wetlands in our city have been continuously strengthened, the wetland ecology has been continuously improved and the Jiayuguan Caohu National Wetland Park has become a paradise for migratory birds, attracting various rare birds such as whooper swans and bar- geese to inhabit every year.
