     The largest-ever chariot pit (战车坑) of relics with carts and horse bones has been discovered in Henan

Province. It may lead to the uncovering of chariot pit groups that could be a key to understanding Chinese

civilizations that existed more than 2,000 years ago.

     Experts said the relics are dated more than 300 years earlier than the famous warriors (武士) in Shaanxi

Province. What excited the experts were two othe r projects that located two huge pits with similar features.

     "It is absolutely a miracle. the se relics indicate that the re could be a tomb group in this area, which is likely

to be important for China's archaeological (考古学的) studies," said Ma Juncai, a leading relic researcher in the

province.

      In ancient China, carts, sheep, spoons and so on were buried to ensure that dead people had a happy

afterlife. the number and quality of the sacrifices indicated the social status of the dead. the custom was carried

into the Qin Dynasty. Emperor Qinshihuang's tomb, located near Xi'an, the capital of Shanxi Province, is

accompanied by thousands of wood or clay figures of warriors and horses. the tomb is probably the most

well-known. 

     The discovered pit measures 10.4 meters long, 8.4 meters wide and 5 meters deep. It holds 20 carts in

different sizes. the smallest one is 1.05 meters long and 1.3 meters wide.

     Experts think that 40 horses are likely to be found as well. Careful plans need to be made to deal with the

demanding uncovering."the clay is very weak and a small misstep can destroy the whole project. That's why

we need to take every step very carefully to protect the se cherished cultural relics," Ma said.
