By sorting out the literature related to constitution and referring to the concept and method of"element",many ancient and modern theories of constitution are deconstructed into multi-dimensional"constitution elements".These constitution elements are divided into two levels:basic and derivative.The basic level is the most basic ele-ment of constitution,including zang-fu organs/body and material.The zang-fu organs/body dimension focuses on the fixed functional units in the human body,and the material dimension focuses on the rheology functional units of hu-man body.The derivative level is the secondary physiological or psychological state in life activities,including emo-tion and qi transformation.The emotional dimension focuses on the state of human psychological activities,and the qi transformation dimension focuses on the state of human physiological activities in cold,heat,dampness,and dry-ness.Based on this,we can further study the influence of factors such as age,gender,region,and social class,on the combination rule of"constitution element",so as to form a more comprehensive classification program of constitution.
