Hong Kong's giant panda twins Little Brother and Elder Sister now have a larger playground where they can run, climb and tumble as much as they want.  

The cubs' home at Ocean Park has been expanded as they grew older and stronger. The upgraded space features a vibrant alpine zone and midland habitat filled with taller trees and diverse landscapes, fulfilling the bears' growing curiosity and helping them bond with mother, Ying Ying.

The new space is set to welcome visitors on May 27.

China Daily's Andy Chong took the photos on Thursday during a media preview.
