A giant panda plays in snow at the panda house in the Siberian Tiger Park in Changchun, Northeast China’s Jilin Province, Dec. 17, 2015. Jiajia, an 8-year-old male, and Mengmeng, a 7-year-old female, are the first giant pandas to live in a high-altitude habitat in China after they were moved from Sichuan to Changchun. The pandas will spend three years in the city, where researchers will gather data and carry out breeding tests. (Photo: China News Service/Zhang Yao)
