YINCHUAN, May 25 (Xinhua) -- Two ancient tombs were discovered at a construction site in the city of Wuzhong in northwest China's Ningxia Hui Autonomous Region, officials confirmed Wednesday.
A tomb dating back to Song Dynasty (960-1127) was found Sunday when workers were digging a cable duct in Litong District, said Ren Shufang, head of the city's cultural heritage authority.
The tomb, containing a female skeleton, was buried three meters deep. A bronze mirror and dozens of coins were also found, Ren said.
The four Chinese characters, chang ming fu gui, meaning longevity and wealth, were carved on the back of the mirror, she said.
Another tomb was unearthed three meters away under a major city road Tuesday. A blue and white porcelain bowl and a black glazed pot were found, based on which the tomb was estimated to be from the Ming Dynasty (1368-1644), said Ren.
Archaeologists concluded that there was no connection between the two tombs.
Multiple tomb clusters have been unearthed around Wuzhong and rare artifacts from various dynasties have been found.
The largest cluster discovered so far included 123 tombs from the Northern Wei (386-557) and Tang (618-907) dynasties. It was excavated in 2005 and 2006 in the city's northern suburbs.
