 Archaeologists discover110 new warrior statues in China After being burried for centuries,110 new warrior statues have been discovered in Xi'an,China. The statues are part of a collection of lifesize figures of warriors and horses called the Terracotta Army (兵马俑) .The group of more than7,000 lifesize clay sculptures was built in210 BC to guard the tomb of China's first emperor,Qin Shi Huang.

  Shen Maosheng,from the Qin Shi Huang Terracotta Warriors and Horses Museum,said archaeologists had located another 11warriors but had not yet begun to dig up the sculptures. "The most significant discovery this time is that the relics that were found were wellpreserved and colourfully painted," Maosheng told AFP.

  The warriors' history The sculptures were discovered by a group of farmers in1974. While digging a well,the workers found three pits filled with the lifelike figures,which were made of a type of terracotta clay. Experts say that long ago,Emperor Qin Shi Huang or?dered the creation of the clay army,along with a 20-square-mile tomb in which to house it. For36 years,700,000 labourers built this underground city. It contains models of palaces and towers,and was protected from intruders (闯人者) by auto?matically triggered crossbows. The city lay buried for more than2,000 years.

  A worldwide attraction Today,people from around the world visit China to see the terracotta warriors. What makes the soldiers so special? Each figure was individually carved,so they have different hairstyles,expressions and facial features. The details make the soldiers appear true to life. Inside the pit,the statues are arranged by military rank. The higher the rank,the taller the statue. The shortest statue is 5 feet 8 inches. The tallest is 6feet 6inches. The lower half of each soldier is made of solid clay,while the upper half is hollow. This makes it easier for the figures to remain upright.

  Great Wall The discovery of Xi'an's110 new warriors comes after a new finding about the Great Wall of China. An archaeological survey revealed the Great Wall of China is more than twice as long as previously thought. The wall originally measured5,500 miles but now measures13,170 miles. Beijing officials plan to open two new sec?tions of the Great Wall and to expand other areas to make room for more tourists.
