A cylindrical object with 12 facets, carved with three characters in each facet and 9 other symbols, for a total of 45 characters.Investigators decipher it as:"Circulating qi:when qi is replete,it accumulates and move downward[to the abdomen,settling there to consolidate.Upon consolidation,qi sprouts and matures,ascending to the heaven [the top of the head. The root of the heaven is at the top,and that of the earth,at the bottom[of the foot. A circulation in the normal direction brings life; in the contrary direction,death." The second illustration is a rubbing of the inscription.
