Yang Mausoleum of the West Han Dynasty, dating back to around 141 BC, was the Mausoleum of Emperor Jingdi and his wife. Except for the main tomb in the middle, there are still 81 pits found located around the main tomb. Many terracotta figures are found, not only of human but also of animals.
Today the discovery of the Yang Mausoleum is still going on. Only some of the pits have been opened.
