Sir,
ST-9 can be found on the neck,just over the carotid sinus...if you try to feel your pulse on the neck,between those muscles,that is the place.
PC-6 can be found on your wrist on your palm side.It,s between tendons approx.4 fingers width back from the wrist crease in the middle of the forearm.
H-6 is located on the inside of the wrist on the small fingers side half of an inch width back from the wrist case.
hopefully this clears thinghs for you sir
