I'm an acupuncturist with a busy practice and I purchased for quick reference in the treatment room for points I rarely use. The Bladder and Small Intestine channels are crossed (misrepresented). When I notified supplier their response was that they were not responsible for misprints and could not do anything. Personally, I feel that if you're selling something functional, it's the supplier's responsibility to check for the appropriateness of the product. Thumbs down on this business.
