What is the difference between a vertical pit tomb and a vertical pit tomb? What is the difference between a vertical cave tomb and a horizontal cave tomb?

The difference between vertical pit tombs and vertical pit tombs lies in their different spatial structures. A pit tomb with a vertical pit is to dig a pit vertically, drop the coffin from the entrance of the tomb, and bury the coffin board with soil. The vertical pit earth tomb is a relatively regular rectangular or square earth pit dug from the ground to make a tomb, which is different from the former in terms of space.

The main difference between vertical cave tombs and horizontal cave tombs lies in their shape and spatial structure. Vertical pit tombs are vertical pits, while the tomb passages and coffin chambers of horizontal pit tombs are basically on the same plane. Among horizontal cave type tombs, it is common for horizontal cave type tombs and horizontal mouth type tombs to use one side of the stone chamber wall as a place to house the deceased. However, horizontal cave type tombs have corridors, and horizontal mouth type tombs use the wall directly as the entrance. There is only a tomb passage outside the stone chamber.

In addition, through the analysis of the tomb shape, it can be seen that these tombs have transitioned from a symmetrical layout of the central axis to a lateral asymmetrical layout, and have evolved from the characteristics of tombs with vertical pits to completely horizontal tombs.
