Giant panda Shu Lan plays at Lanzhou Zoo in Lanzhou, capital of northwest China's Gansu Province, March 16, 2017. The 23-year-old giant panda will leave Lanzhou on Thursday to return to its hometown in southwest China's Sichuan Province due to health concerns. The Lanzhou zoo held a farewell party for Shu Lan on Thursday morning. Many locals came to say goodbye. Experts said Shu Lan is in normal health, but concluded that she has shown some symptoms of aging, such as weight loss. Her age is equivalent to about 70 human years. Therefore, experts suggested sending Shu Lan to a conservation and research center for Giant Panda in Sichuan to help her maintain her health. (Xinhua/Fan Peishen)
