White swans gather at the Nanhai Wetland scenic area in Baotou, Inner Mongolia autonomous region, following the city’s spring snow on Feb 26. Flocks of swans come to Baotou every spring thanks to the city’s efforts at environmental protection over the past few years. The swans feed on the straw and grain on the shoals and will leave for another location after around a month. [Photo/Baotou Daily]
