There are three types of vacuity and three types of repletion in humans. What does this mean?

The answer is: There is vacuity and repletion in the pulse image, vacuity and repletion in the disease, and vacuity and repletion in diagnosis. Vacuity and repletion in the pulse image: when the pulse is soft and soggy, it is vacuity; when the pulse is tight and forceful, it is repletion. Vacuity and repletion in the disease: when qi disperses outward, it is vacuity; when qi gathers inward, it is repletion. Speaking a lot is vacuity; not speaking is repletion. When the disease progression is slow, it is vacuity; when it is rapid, it is repletion. Vacuity and repletion in diagnosis: when the skin is soft and soggy, it is vacuity; when the skin is firm and solid, it is repletion. A sensation of itching is vacuity; a sensation of pain is repletion. When there is pain externally and comfort internally, this is external repletion and internal vacuity. When there is pain internally and comfort externally, this is internal repletion and external vacuity. Therefore, there are distinctions between vacuity and repletion.
