Panda Cao Cao is seen with her panda cub at the Hetaoping panda base in Wolong, southwest China's Sichuan Province, Aug. 20, 2019. A pair of male panda twins were born to both captive and wild parents in Sichuan Tuesday, according to China Conservation and Research Center for the Giant Panda. Panda Cao Cao, 17, gave birth to the twins. Rescued from the wild in 2002, Cao Cao grew up in captivity. She was released into the wild in March and mated with a wild panda in April, as scientists tried to increase genetic diversity of captive pandas, according to the center. (Xinhua)
