Was the tomb of Emperor Wendi of Sui Dynasty stolen?

Wendi's mausoleum was stolen in the early years (probably in the late Sui Dynasty or the Tang Dynasty).

The tombs of Emperor Wendi of the Sui Dynasty and Empress Dugu of the Founding Emperor of the Sui Dynasty, formerly known as Tailing, were built in the second year of Sui Renshou (AD 602) and located in Wangshang Village, Wuquan Town, more than 20 kilometers southeast of Fufeng County, Shaanxi Province. Discovered and restored in the Qing Dynasty, it is now called "Tailing".

The tomb is 27.4 meters high, bucket-shaped and rammed. The ground floor covers an area of 26,560 square meters. The top of the mausoleum is flat and 38 meters wide from north to south. The bottom of the mausoleum has been excavated for 3-5 meters, and the remaining length is east-west 166 meters and north-south 160 meters. The rammed earth wall around the tomb has been basically destroyed, but there is still a residual wall in the north city, which is about130m long, the highest point1.2m, and the residual width is 5.5m.. The rammed layer is clear and the rammed nest is obvious. After preliminary drilling, the tomb is 756 meters long from east to west and 652 meters wide from north to south, with a total area of 492,900 square meters.
