File photo taken on April 20, 2011 shows the duplicate of a rock scenery spot named "Queen's Head" in the Yehliu Geopark, southeast China's Taiwan. The unique rock, shaped by wind erosion for nearly 4,000 years, may collapse in ten years as its middle part becomes thinner and thinner. And thus the geopark has built a duplicate of the rock for the sake of those who could appreciate the landscape if it would disappear. [Xinhua/Gong Bing]
