This 2,000-year-old tomb is like a huge underground palace
The Xuzhou Guishan Han Tomb is the tomb of Liu Zhu, the sixth king of Chu in the Western Han Dynasty. The tomb is 83 meters long from east to west, 33 meters wide from north to south, and has a total area of ​​more than 700 square meters, almost hollowing out the entire mountain.
The walls of the corridors in the Han tomb are polished and smooth, just like the effect of machine cutting, which is shocking.
The Xuzhou Guishan Han Tomb is quite large, almost hollowing out the entire mountain, and the stone of the mountain is very hard. What is amazing is not only the huge tomb chamber, but also the corridors built in the mountain.
The Guishan Han Tomb has two corridors, the distance between the corridors is 19 meters, and the error is only 1/16000.
I don’t know how such craftsmanship and precision were achieved with the technical level 2,100 years ago.
