Clay dragon heads, glass beads help connect dots in history

The Chinese Academy of Social Sciences announced on Tuesday that restoration has been completed of two precious pottery dragon heads unearthed from the Xiong'an New Area in Hebei province.

The restoration work was carried out by the academy's Key Laboratory of Archaeological Sciences and Cultural Heritage.

Pieces of the rare clay dragon heads, which are believed to have been used in Tang Dynasty (618-907) architecture, were found in October amid the ruins of an ancient city in Xiong'an.
