A group of artificially bred panda cubs have been put together for the first time since their births in the city of Chengdu in south-west China's Sichuan Provinces.
The 14 panda cubs, born between July and September this year, are currently being raised in two delivery rooms in the the Chengdu Giant Panda Breeding and Research Base.
Among the 14 cubs, the eldest one, Meng Meng, is four times heavier than the youngest, Ya Yi. In fact, the two were born only 40 days apart.
The most dangerous period for the panda cubs is during their first 10 days, when they are most susceptible to diseases or may die from improper feeding.
Panda cubs will not open their eyes until about 100 days after the birth.
This year the Chengdu facility has seen 17 artificially bred panda cubs born, 14 in China and three others in the United States and Spain.
