Editor's Note:
A senior giant panda named Gaogao just finished his 15 years of sojourn at the San Diego Zoo in the United States, and met the public on December 3. The 28-year-old panda, which is equivalent to about 98 human years, is now living in the China Conservation and Research Center of Giant Pandas in Southwest China’s Sichuan Province.
