Giant panda Jia Jia plays at the Ocean Park in Hong Kong, May 27, 2016. The average life span of captive pandas is 25 to 30 years. Born in 1978, Jia Jia achieved two Guinness World Records titles last year as being the oldest panda ever in captivity and the oldest panda living in captivity, while 30-year-old An An became the world's second oldest male panda under human care. Apart from An An and Jia Jia, the central government also presented Ying Ying and Le Le, a younger pair of pandas, to Hong Kong in celebration for the 10th anniversary of the establishment of the special administrative region. The two pairs moved in to Ocean Park in 1999 and 2007 respectively, and nearly 43 million people had visited them as of April 2016. (Photo/Xinhua)
