What is the scale of Bigan's tomb?

The wind king saw some tricks and jumped off the deer platform and died. The imperial edict is to set up a mourning hall for Bi Gan, send 400 Qiang slaves, and build a tomb for Bi Gan in the northern military attache city of Chao Ge.

A few days later, Bigan Tomb was built into a stone tomb with an area of160m2 and a depth of 8.5m.. There are four tombs in the east, west, north and south, and the tomb building is like a chess room before death.

On the day of the funeral, the king personally divined, and on an auspicious day, he personally led Wu Wen White to attend the funeral.
