A set of panda triplets, known as the world's only surviving trio（三胞胎）, have opened their eyes for the first time more than a month after their birth in a Chinese zoo.

The mother panda, named Juxiao, meaning "chrysanthemum smile", delivered the triplets（三胞胎之一）at Guangzhou's Chimelong Safari Park in the early hours of July 29. And the trio's births were seen as a "miracle" because of the low reproductive（生产，繁殖）rate.

The three cubs covered with white and black fur are now squealing moving about with their eyes open. The second panda to be born was the first to open its eyes, followed by the lastborn and then the firstborn. Each one is starting to show its own individuality. For example, the third one is the liveliest. The cubs' next stage in development will be to start walking. The gender of the cubs cannot be determined until they grow older.

The first known case of triplets from a giant panda was recorded in 1999, when a 15-year-old mother gave birth in the southwestern Chinese city of Chengdu. However the youngest of the trio died after living for just three days because of a bladder disorder.

Pandas, whose natural habitat lies in mountainous southwestern China, have a notoriously low reproductive rate and are under pressure from factors such as habitat loss. China now only has about 1,600 pandas living in the wild.

Their normal breeding season is mid-April to May.
