A four-month-old panda, center, is examined before it is released into the wild by panda researchers who dressed up as a giant panda to prevent the panda cub from seeing human shape at Wolong Giant Panda Reserve Centre in Wolong, in southwest China's Sichuan province. Panda researchers in the province are working to reintroduce giant pandas into the wild within 15 years, after successfully breeding them in captivity.
