　　In the spring of 1974, Chinese archaeologists(考古学家)made a great find in Xi'an, Shanxi Province, when they unearthed(挖掘；挖出)the pottery statues of imperial(帝国的；皇帝的)guards buried in the Tomb(坟墓)of the First Emperor of the Qin Dynasty over 2,000 years ago．The pit consists of more than seven thousand pottery warriors, horses and wooden chariots(双轮战车)in life size．The arms they hold are altogether real, and some of the swords are still very sharp．The news of the findings spread far and wide．In the past years it attracted tens of thousands of visitors including foreigners, overseas Chinese and compatriots(同胞)from all over the world to Xi'an, which boasts of having been the capital of several dynasties by the name of Chang'an since ancient times．

　　The pottery army is well worth a visit．All the pottery warriors and horses are so vivid and lifelike that you could almost feel them breathing．Obviously the craftsmen in the Qin Dynasty were very skillful．Their skills had reached the highest level．Many foreign visitors admire and praise them as a wonder．The former French Premier spoke highly of them．“There have been seven wonders of the world：now the Pottery Army in Qin Tomb is to be added,”he said,“Not to see the pyramids is not to see Egypt at all, while not to see the Pottery Army is not to see China at all．”His words admirably(令人钦佩地)sum up the impressions of all who have seen this wonder of China and of all the world．
