Through sorting out the development of meridian points and the standardization of extraordinary points in dynasties, two objectives are discovered in the standardization of extraordinary points starting from the Tang Dynasty. The points with extraordinary effect are selected points and transferred to meridian points and the commonly-used key points are selected and developed to be standardized acupoints. Hence, 3 approaches are summarized. Approach No.1: a large number of "meridian-outside" points that are the potential supplementation but not included yet in meridian points are supplemented to meridian points. Approach No.2: based on the specified requirement, the key points are selected from the acupoints with determined locations and names, which is developed to be the standard of acupoints. Approach No.3: the acupoints with extraordinary effect are selected from the "meridian-outside" points and these points are collected for the formulation of the standard of extraordinary points. The latter two approaches provide for the development direction of teaching and standardization in the future.
通过对经穴形成和经外奇穴历代标准化的梳理，发现自唐代开步的经外奇穴标准化有两个目标，即精选奇效穴转为经穴和精选常用要穴形成统一的腧穴标准，由此出现3条路径：路径一，从大量“经外”穴中精选能补经穴之未备的穴作为经穴之补充；路径二，从所有有固定位置和名称的腧穴中按统一标准精选要穴，形成一个统一的腧穴标准；路径三，从经外穴中精选奇效之穴，制定出与经穴标准并行的经外奇穴标准。后两条路径分别是未来教学、标准化工作的建议发展方向。.
