Giant panda cub Bei Bei sleeps at National Zoological Park in Washington DC, the United States, Jan 16, 2016. Born on August 22 last year, Bei Bei has been the third child of his mother, Mei Xiang and father Tian Tian. Bei Bei's weight has reached 25 pounds and started to nibble on bamboo. But he is still fed by his mother's milk, Marty Earie, a zoologist at the National Zoo, said. He has been taking care of Bei Bei since he was born. (Photo: China News Service/ Zhang Weiran)
