1. Why right and left branches of the large intestine meridian cross each other on the midline, unique exception over 12 main meridians?
2.  Why the kidney meridian path forms a circle on the medial aspect of the foot, whereas the bladder meridian does not the same on the lateral aspect? 
3. Why the small intestine meridian draws a zig-zag in the shoulder, scapular area?
4. Why amongst the back-shu points is listed Dushu, referring to Governor Vessel, even though TCM does not connect it to a specific organ? Is there a plausible explanation for why it finds just between Xinshu (Heart point) and Geshu (Diaphragm point) and not elsewhere? If it is an organ which would it be? Is there in the body a Governor organ? The answer is yes, there is!
