Video: 14 giant panda cubs make public debut in China
Cubs born between July and September of this year
The cubs were born between July and September this year and are being raised in two delivery rooms.
The eldest cub, Meng Meng, is four times heavier than the youngest, Ya Yi, despite being born just 40 days apart.
The first 10 days are the most dangerous period for panda cubs, as this is when they are most susceptible to diseases.
Panda cubs do not open their eyes until about 100 days after birth.
