DUJIANGYAN, July 17, 2016 (Xinhua) -- Photo taken on July 15, 2016 shows aged panda Yuanyuan at the Dujiangyan base of China Conservation and Research Center for the Giant Panda in southwest China's Sichuan Province. There are eight giant pandas with an age above 20 living at the Dujiangyan base. For the real age of giant panda equals to four times of that of human beings, so the age of 20 years old is equivalent to 100 years old among humans. The Dujiangyan base, which undertakes the work of disease control and prevention for pandas, also acts as a nursing home for aged pandas. (Xinhua/Xue Yubin)
