Visitors look at the hollow camphor tree in front of the primary school of Xianglingjiao village in Wuyuan County, east China's Jiangxi Province, March 24, 2014. The old camphor tree, three-odd meters in diameter, survives a lightning stroke. With only part of the trunk and hollow inside, the tree remains lush. Thus, the tree is called "tough tree" by the local people and listed as one of the most important protection objects by the local government. [Photo/Xinhua]
