From the radial styloid process (Gaogu) to the fish margin (Yuji), a distance of one cun is measured, named Cun Kou (Inch Port); from Cun Kou to Chi Ze (尺泽), it is named Chi Ze, thus also referred to as Chi Zhong (尺中). The area between Cun Kou and Chi Zhong is named Guan (关). Yang Qi emerges here, Yin Qi enters here, with Guan serving as the boundary. It is further stated: Yin occupies one cun within Chi, while Yang occupies nine fen within Cun. Moving six fen inward from Cun Kou defines the Guan section; moving another six fen inward from Guan defines the Chi section. Thus, the three sections together measure one cun and nine fen.

The Right Kidney is located at Chi on the right hand, belonging to the Hand-Jueyin (Pericardium) Meridian, which pairs with the Hand-Shaoyang (Sanjiao/Triple Burner) Meridian.
