Analysis on the different styles of expression of acupoint selection and application for "Jue Toutong"(severe headache) and "Jue Xintong"(cardiodynia with cold limbs) and the development of expression styles of acupoint selection and treatment of "Xintong"(cardiodynia) and "Jue Xintong" shows that the selected meridians for treatment of the related disorders commonly-seen in the ancient acu-moxibustion literature are

in fact

referred to the acupoints on the distal part of the four limbs in a certain neurosegment.The closer to the distal part of the four limbs

the higher is the identity of the acupoints in indications.The limit of the distal part is basically located at the wrist and ankle joints.If this identity of acupoint indications is referred to categories of diseases or syndromes

the range of acupoints on the four limbs may be extended to proximal part of the elbow and knee joints

and the representative acupoints are Five Shu-Points(Well-point

Spring-point

Stream-point

River-point and Sea-point).
