Point name meaning:
In ancient China, 都 (dū) was a name used for a large or important municipal district. The character 大 (dà), large or great, may be a reference to the fleshy part of the large toe where the point is located, or simply an adjective amplifying the importance implied by 都. The point name reflects both this point’s significance (which is due, in part, to its being the fire [mother] point of the earth channel) and its location on the great (大 dà) toe.
This point might also be rendered as Great Pool, for it stores earth qì just as a pool stores water. See
