No object with the name of Empress Huayang was found.
Debated. A study says this royal tomb is the most likely place for her, but that is not proved.
The tomb is the Shangzhaoyao Qin Mausoleum, in Weicheng District of Xianyang, near Xi'an Xianyang International Airport, in Shaanxi, China. Bones from side graves gave dates from 389 to 208 BC. The cemetery is about 600 by 580 metres. It has a central tomb, inner and outer ditches, extra graves, and sacrificial pits. Finds include pottery, bronze, iron, jade, agate, and glass. The central tomb had been looted.
Old accounts say she was buried with a king at a different place, and this tomb still has no inscription of her name.
