Polar bear tamer (5)

Working with polar bears may sound like a very cool job to most of the people, however, it is also a very dangerous job to get along with 500 kilograms pure carnivores. Especially when tamers need to take polar bears' temperature, it is just like a mission impossible for a new comer. At Harbin Polarland, there are 11 doors set for the polar bears' home, and each directs to a different place like the exhibition area, dinning area, or sleeping area. "If you open the wrong door, it's very possible he runs out of the cage."
