Three patients, who are workers on Yongshu Reef in the South China Sea, arrive at Phoenix International Airport in Sanya, south China's Hainan Province on Sunday. The three emergency patients, who were suffering from gastrointestinal bleeding, a lumbar fracture and appendicitis, respectively, had to be flown by a navy jet to a hospital in Sanya due to a lack of medical facilities to treat their conditions on the reef.
