Jia Jia was given as a gift to Hong Kong by mainland Chinese authorities in 1999, alongside male panda An An, who will soon turn 29.

The zoo will also offer some admission and concession specials in honor of the panda twins' birthday. Ya Lun and Xi Lun were born 47 minutes apart on Sept. 3, 2016.

Another giant panda, Meng Meng, celebrated her tenth birthday on July 10. The zoo prepared a delicious ice cream cake made out of beetroot as a gift for the chubby bear.
