　　The San Diego Zoo has been a lovely home for giant pandas since two of the black­and­white pandas came to visit in 1987. This week there was snow in San Diego-well, at least for a lucky group of giant pandas.

　　Over 15 tons of snow was blown into the San Diego Zoo's panda area on Tuesday morning to give the endangered pandas a chance to play. They would experience the snow just like living in their natural habitat.

　　The snow day was a first for Xiao Liwu whose name means "Little Gift". He was the sixth baby panda born to Bai Yun. Xiao Liwu was jumping on Mom, playing with her and getting used to being thrown in the snow by mama panda. Jennifer Becerra，San Diego Zoo keeper said，"He was really enjoying the snow and running around. I've never seen him so happy."

All the San Diego Zoo's giant pandas are from China, as part of a long­term captive breeding (人工养殖) program. Four of Xiao Liwu's brothers have already been moved from California to China.
