Qi Blood TCM and Western Anatomy/Physiology

I love coincidences, do you?
...ohhh and it seems that the Chinese are right again...!

Qi "lives", is transported through blood...
"it is at the extremities (Jing-Well points) that the Qi changes direction" (TCM theory)

Curiously, however, the perforating veins in the foot lack valves and thus do allow bidirectional flow. (Western anatomy/physiology)

The direction of flow in the 5 Shu-Point theory
is not as important as the quality of energy described at each of the points. The Jing-Well points, for example, are situated on the tips of the fingers or toes, where there is little flesh. The Qi here is shallow and narrow, yet
dynamic, pouring forth like a spring or a well. The volatility of the Qi at these points is emphasised by the fact that in the theory of the circulation of the 12 channels,
it is at the extremities (Jing-Well points) that the Qi
changes direction and where Yin and Yang channels
transform into each other.

Curiously, however, the perforating veins in the foot lack valves and thus do allow bidirectional flow. According to Meissner et al. (2007), the calf muscle pump is the most significant and has the largest capacitance, but is primed by muscle pumps in the foot.
