Fujian Normal University graduates form a "band" for their underwater graduation photos shot at a swimming pool in Fuzhou, capital city of East China's Fujian province, June 19, 2016. The graduates spent over two months to prepare for their final pictures as it's not easy to pose below the surface in 4.5 meter deep water, according to graduate Liang Yedan. But Liang believes the photos will be his best graduation present. [Photo/CFP]
