Shaped in the form of an aeroplane, an attendant opens the door to the entrance of a cave that was once the headquarters of former Chinese Communist military leader Lin Biao, located in mountains on the outskirts of Beijing July 16, 2012. The cave has been turned into a 'Military Bar' using old military ordnance as furniture including sandbags, helmets, artillery shells and land mines. Marshal Lin Biao used the cave as his military headquarters in 1968 shortly before he died when his plane crashed in Mongolia following what appeared to be a failed coup to oust Chairman Mao. He was shortly after his death officially condemned as a traitor by the Communist Party of China. REUTERS/David Gray
