What is the length, width, height and size of the tomb of Yin House?

The length, width and height are 6.3m, 1.6m and 2.4m respectively. The tomb of Yin House is basically to dig a vertical pit from the ground, open a horizontal pit at the bottom of the vertical pit, and then build a tomb in this horizontal pit with a coffin in it.

Yinzhai, the name of geomantic omen, is the place where ancestors' coffins are buried (different from graves) and where ancestors can rest in peace, so it is called Yinzhai. Yang Zhai should look at Feng Shui, and Yin Zhai should also pay attention to Feng Shui. The ancients believed that burying ancestors in land with excellent feng shui would bring good luck to future generations. On the other hand, if the geomantic omen is not good, everything will go wrong for future generations. What's more, bad luck will continue and families will break up.
