Beijing, July 25 (Youth.cn) - Photo taken in Tiaozini grass wetland in Jiangsu Province. On a hot summer day, wild elks were seeking foods while playing in grass. Above the wetland, groups of migrant birds flied over in blue sky. Lush grass contrasted finely with blue sky and water, unfolding a beautiful summer picture of vigor and vitality. These years, with ecological environment continuously improves, more and more wild animal groups come here to stay, breed and live. Photo/VCG
