Long ago the reclusive scholar Kuai Liang said: “An acquaintance was suffering from a tumour on the forehead; the physician, having cut it open, found a qi (a chess-like game) piece of black stone; even when struck with a heavy axe it could not be damaged. Again, there was one whose shin grew into a tumour; because, having been bitten by a ferocious dog on arriving at a relative’s place, it gnawed directly at the growth, inside it they found more than a hundred acupuncture needles, all suitable for use; the illness cleared up too.
