Hong Kong’s youngest celebrities, a pair of six-month-old panda cubs, met with their adoring fans in their first public appearance, on Sunday.

Hong Kong has called on members of the public to help name the city’s first locally-born giant panda cubs. The cubs are twins and turned six months old on Saturday, an occasion that was also marked by their first public appearance. They are kept at Ocean Park, which now houses the largest number of pandas in captivity outside mainland China.
