All four giant pandas that have called Zoo Atlanta home landed back in China on Saturday. It's been 23 years since the parents came to Georgia.

A pair of giant pandas is set to arrive at the National Zoo on Tuesday less than a year after the Washington zoo sent Mei Xiang, Tian Tian and their cub Xiao Qi Ji back to China.

Grace Sheng and her husband Evan Affinito drove three hours from Columbia, South Carolina, to wish Zoo Atlanta’s four giant pandas farewell this past Saturday. At noon, they were greeted by a line that stretched several hundred feet all the way back to the rhino exhibit.
