Over 300 swans descended on a man-made lake in Yuxian County of north China's Shanxi Province on Monday as warmer weather set in, drawing crowds eager to capture the moment with their cameras.

Visitors watched as the swans foraged and played across the lake, creating a lively scene that attracted dozens of photography enthusiasts. Ecological projects in Yuxian County have improved environmental quality, boosting both the diversity and numbers of migratory birds.
