Dear Professor Price,
So sorry for the incomplete answer sent previously, it was submitted all by mistake.
Now the answer to your question.
It IS the printing mistake for the lack of the inserting depth of point Zusanli (ST 36), so I will correct it as soon as possible.
In clinic, the point is needled for 1 to 1.5 cun, or even deeper, since it is pretty safe. Personally I think it's all up to the need of the needling sensation and the body build of the patients'.
Generally speaking, the points on the arms and legs are pretty safe, so they can be needled deeper, so the depth of 1 to 1.5 cun would be alright, I mean for Chinese patients. While for the European and American patients, you should do it according to their reaction, for they are more sensitive than Chinese patients.
That's my personal understanding and you can find your own experience.
