The little pandas appeared at "Discovering Twin Cubs", jointly arranged by the United Nations Development Program (UNDP) and the Chengdu Research Base of Giant Panda Breeding to call on panda fans and people across the world to protect wild animals and plants such as pandas.
Patrick Haverman, deputy country director at UNDP, attended the event and declared that twin cubs born to Qinhe, a 14-year-old panda, in September have been designated as the image ambassadors of the UNDP.
In 2015, a total of 15 panda cubs, including the 12 twins, were born in the Chengdu research base, a new record.
Although experts are not sure about the exact reason for the success of the birth of so many twins, Hou Rong, a member of the base staff, guessed that it might be related to better feeding and management in the breeding centre, state-run Xinhua news agency reported.

The fertility of captive giant pandas is even lower because they do not move much, experts said.
