The most recent hanging coffins were made up to about 400 years ago in the middle and later periods of the Ming Dynasty (1368-1644), while many of the earliest ones date back 1,000 years to the Song Dynasty (960-1279).
To date, the earliest hanging coffin was one found in the Three Gorges area, dating back about 2,500 years to the Spring and Autumn Period (770 BC- 476 BC)
People keep questioning why did the Bo people bury their dead in hanging coffins? How did they do it? And why did the Bo people disappear?
Some believed the coffins must have been lowered down with ropes from the top of the mountain.
