In early winter, wild flamingos fly to Yuncheng Salt Lake in Shanxi Province, embarking on a journey of wintering and roosting. In recent years, Yuncheng City has continued to promote the ecological restoration project of "returning salt to the lake". Through measures such as dredging the water system, ecological water replenishment, forming professional patrol teams, and carrying out the "Clean Lake Action", the water quality of the salt lake has been significantly improved, and rich food resources such as saltwater shrimp and algae that flamingos love to eat have been nurtured. It has become an important "ecological relay station" on the migration route of migratory birds. (New Society)
