Juque. Giant, big also. Que, tong deficiency, deficit also.

The name of Juque means that the moist heat and moisture in the upper part of the chest and abdomen gather here. In the depression at the junction of the chest and abdomen, there is no qi and blood from the upper and lower parts of any pulse to this point, and the qi and blood in this point are damp and hot water vapor from the upper part of the chest and abdomen. Because of its heat, this gas can neither rise nor fall, and it is aggregated at this point. This point gathers external water vapor like a huge vacancy, hence the name Juque. The meaning of a giant name is the same as that of a giant que.
