California is celebrating the public unveiling of an exhibit at the San Diego Zoo featuring two giant pandas brought in from China in a big way, with Gov. Gavin Newsom (D-CA) proclaiming a day of celebration in their honor.

The zoo unveiled its Panda Ridge exhibit on Thursday, a month after the two pandas, Yun Chuan and Xin Bao, landed in the United States. The pandas are the first to enter the U.S. in 21 years.
