Chinese and British climbers have found a cave hall at the bottom of a 200-metre long sinkhole in Guangxi, China, state TV says.

The large cave hall is estimated to be 6.7 million cubic metres.

The team lowered themselves into the sinkhole using a single rope.

It is hoped the discovery will help geologists to understand the region better.
