The polar bears Escka and Cissy are twins brought in and bred by the park from Thailand in 2013. They are now 11 years old that is less than 30 years old in human terms. Polar bears live to be around 25 years old in the wild, but longer in captivity. In addition to feeding them beef, chicken and fruits and vegetables, we also provide Russian herring and prepare special food for them during festivals, such as honey zongzi for the Dragon Boat Festival.
