Twin polar bears respond to nanny's local dialect

(Ecns.cn)—Two visiting twin polar bears, one boy and one girl, have rocked visitors in Dalian of northeast China's Liaoning Province, reported Wuhan Evening News on Friday.

The twins, hailing from central China's Wuhan city, are reported to be able to stalk the catwalk, tease each other and amuse themselves and others with pranks. Most surprisingly, these two will only respond to the keeper's dialect when dinner time is being announced.
