In 1974, farmers digging a well in Xian, China, found some pottery which led archaeologists to an underground palace for Emperor Shi Huang. It took about 7,20,000 workers at least 39 years to build the entire structure and many treasures were buried with the emperor. Thousands of terracotta soldiers have been standing guard for the past two thousand years to protect the burial site and these sculpture warriors are an amazing sight. These life-size pottery soldiers have hollow bodies and only the legs of the soldiers are solid pottery.
Each soldier weighs about 250 pounds and the warriors do not all look alike; they have different ears, noses, hairstyles, beards and moustaches. There are soldiers in different positions: standing, sitting and kneeling and soldiers who look proud, angry, kind and even timid.
The designs and the colours of the clothing are different as well. Some warriors were sculpted wearing armour while others carry different weapons, such as metal spears, swords, or wooden weapons.
The emperor wanted his grave to be guarded for all eternity by a replica of his own army. Over time, most of the colour has faded from the uniforms which may have been originally painted bright red or green.
Other things found at the site included lifesize chariots and horses made of bronze. The horses have large nostrils and big eyes and look like they are waiting to go into battle! In reality, however, liquid mercury was used to keep away intruders.
Many people think that Emperor Shi Huang's tomb is the eighth wonder of the world.

B Soldiers with metal weapons
C Horses and chariots
