The Guardian Chinese archaeologists have unearthed evidence that a foreign worker helped build the Terracotta Army mausoleum, the resting place of the country's first emperor, who died more than 2,200 years ago.

The remains of the worker, described as a foreign man in his 20s, were found among 121 shattered skeletons in a labourers' tomb 500 metres from the mausoleum in the north-western city of Xian, the state-run Xinhua news agency said.
