Visitors examine a terracotta sculpture at Emperor Qinshihuang's Mausoleum Site Museum in Xi'an, Shaanxi province, on Wednesday. The special exhibition features relics unearthed from the K0007 burial pit of the mausoleum, which mainly consists of non-military elements, such as bronze birds — swans, cranes and geese — and a terracotta imperial "orchestra "meant to entertain the emperor in the afterlife.
