Other established corresponding point combinations are a collection of experiences and other theories combined. For example. Zusanli (ST36) combined with Sanyinjiao (SP6) is based on the theory that qi and blood share the same source.
The Baihui (DU20) and Fengfu (DU16) pairing, however, is founded on the shu-stream points above and below the brain. As for the combination of Guanyuan (RN4) and Zusanli (ST36), the purpose is to fortify the congenital and acquired qi. All of these
combinations provide an example of how points can be combined based on the treatment intentions.
