This photo taken on February 11, 2012 shows a visitor taking a photo of a ram named Changmao (R), who has formed an “inseparable bond” with a female deer named Chunzi (L), at the Yunnan Wild Animal Park in Kunming, southwest China’s Yunnan province. Staff at the wildlife park turned to the country’s half-a-billion Internet users for advice after Changmao and Chunzi began mating, and now a wedding has been planned on Valentine’s Day for the couple.
