CHONGQING (CQNEWS) -- Last weekend, many giant panda fans gathered at Chongqing Zoo to make birthday cakes, sing happy birthday songs and offer birthday greetings to celebrate the 38th birthday of the giant panda “Xinxing”.

According to the introduction, Xinxing is the world’s oldest existing captive giant panda. In general, a giant panda’s age of 1 year is roughly equivalent to a human’s age of 3-4 years, so the 38-year-old Xinxing is equivalent to a human’s age of 110-140 years.
