Giant panda Qiao Qiao and one of her cubs were brought back to China Conservation and Research Center for the Giant Panda in Sichuan on Thursday.
Qiao Qiao, 10, was released into the wild in March.
She gave birth to a pair of male twins on Sept. 16 after a successful mating with a wild panda in April.
Wu Daifu, head of the center's Hetaoping base, said they retrieved the mother and son to protect them against the harsh winter.
