In this combination photo taken on July 18, 2013, an archeological worker repairs dilapidated pieces of a terracotta warrior at the Emperor Qinshihuang's Mausoleum Site Museum in Xi'an, capital of northwest China's Shaanxi Province. The 2,200-year-old mausoleum was discovered in Lintong District, 35 km east of Xi'an, in 1974 by peasants who were digging a well. The Chinese terracotta army buried around the mausoleum was one of the greatest archeological finds of modern times. (Xinhua)
