The twin panda cubs Pit and Paule, born in 2019, are preparing to return to China from Berlin Zoo in the next few days. To commemorate the brothers who grew up there, the zoo on Saturday held a special send-off ceremony. Fans from Belgium and France also came to bid farewell to the giant pandas. A suitcase full of letters and cute drawings from German children will accompany them home. Andreas Knieriem, director of Berlin Zoo, praised panda conservation as the pinnacle of modern species protection.
