HADONG, South Gyeongsang Province - As the guide at Bear Village makes beckoning sounds into her microphone, two large Asian black bears emerge sluggishly from their abode inside a concrete cubical structure. One female bear, aged 21 (147 years old in human age, according to Choi Da-hee, the guide), approaches the foot of the eight-meter-high wooden observatory deck in the middle of the compound and stands on her hind legs to figure out what is on the deck.
