The peculiar life in Zhongdong Miao Village

Tourists from all over the world come to this surreal village in Sanmenxia, China to marvel at the unique complex of caves that have been housing people for hundreds of years. Ruptly got a bird's-eye view of the underground village of man-made caves which continue to be inhabited to this day.

HONGDONG, China (Reuters) - For Wang Fengguan, a man's cave is his castle. He lives in a huge one -- and he has no intention of leaving. Neither do any of the other 20 families in his village.

"Where else would we go?" said Wang, sitting in his house, built in the cave where his family has lived for more than half a century, deep in the poor, remote southwestern Chinese province of Guizhou.

"This is our home. We are used to it," he added, in uncertain sounding Mandarin.

Wang's village of Zhongdong -- which literally means "middle cave" -- is built in a huge, aircraft hanger-sized natural cave, carved inside a mountain over thousands of years by wind, water and seismic shifts

Although the idea of living in caves has gone out of fashion in the last few thousand years, that doesn’t stop people in different parts of the world who continue the tradition. These 21st century troglodytes live all over the world, in the United States, Europe and Asia.

There is a documentary on the one in China. But I don't have the name of it, to search it.
And documentaries or links on this subject would be appreciated.

There's a lot to be said for living in a cave... no a/c or heating bills for instance.
