     In the spring of 1926, Yan Qingbao,  a 43-year-old farmer, discovered a circular piece of jade(玉)  

while digging a hole. Driven by curiosity, he dug deeper and found a group of about 400 colourful jade

pieces.

     At the time,  he had no idea that his discovery would be as important as other wonders of the world

such as China's Great Wall and Egypt's pyramids. Since then more than 10000 relics, dating back to

between 5000 and 3000 BC have been unearthed at Shanxingdui. These relics include gold, pottery,

bone tools and ivory objects. They prove that Shanxingdui contains the ruins of an ancient city that was

once thepolitical, economic and cultural center of the ancient Shu Kingdom-the old name for Sichuan.

     It has helped modern historians realize that Sichuan's human history goes back more than 5000 years. And, located on the upper part of the Yangtze River, the site challenges the common. idea that Chinese

civilization rose from a single source-the Yellow River valley.

     Shanxingdui was named the Scientific Education Base for China's Youth in March this year.

     But still, only four of the Shanxingdui Ruins 12 square kilometers have been uncovered.  Who knows
