you are correct-mak, is a vessel, as in blood vessel, or meridian, and the points are along the vessels.Yuet is blood, and again, it is used to refer to the points. From what I have been told, both mak and yuet are referring to points. They are mostly interchangeable. It is a common term, rather than a technical term. It's funny, a word like Sung, can be translated into pages of descriptions, and other words are somewhat vague. Very difficult language to understand. My Sifu gets frustrated with my poor Chinese.
