I BOUGHT IT FROM LOOKING AT HIGH STAR RATING, HOPING TO LEARN MORE ADVENCE AMMA TECHNICS AND TO MY DISAPPOINT, IT HAVE A VERY LITTLE AND BASIC TECH. WITH LOT OF TCM THEORY. THE MODERN AMMA IS VERY CLOSE TO THE SWEDISH AND THE DEEP TISSUE MASSAGE TOGETHER, PRACTICED WITH OR WITHOUT TCM THEORY. THE MODERN AMMA IS NOT DESIGN TO BE CLINICAL, RATHER PLAIN MASSAGE. THIS AMMA THERAPY IS NOTHING MORE THAN AMMA PLUS TCM THEORY,MAKING IT MORE CONFUSING AND MADE AMMA THERAPY AS REGISTERED MARK IS LIKE SOME HOW I PUT SWEDISH MASSAGE AND TCM THEORY TOGETHER, MAKING IT SWEDISH THERAPY WITH REGISTERED MARK AND NOBODY CAN USE THAT NAME WITHOUT MY PERMISSION. BUT THE QUESTION IS CAN I DO THAT. IF I DID THAT SOMEONE WILL BEAT THE DAYLIGHT OUT OF ME.
