Giant pandas Lun Lun and Yang Yang, who were kept at Zoo Atlanta in the United States, along with their twin offspring Ya Lun and Xi Lun, arrived safely in Chengdu, Sichuan province on Sunday evening, the Chengdu Research Base of Giant Panda Breeding said.

Male Bao Li and female Qing Bao, both 3 years old, will fill the large void left at the National Zoo’s now-renovated panda exhibit when their predecessors – a couple that had been there for 24 years and their cub – were sent to China in November at the expiration of their lease.
