三部者。上中下。即寸关尺也。每部三候。各自分天人地。
上部天以候头角。上部人以候耳目。上部地以候口齿。中部天以候肺。中部人以候心。中部
地以候胸中。下部天以候肝。下部人以候脾胃。下部地以候肾（九候虽有数说。不如此说易晓。今
亦难用。姑存之。）
王子亨云。一位有三候。浮取之属阳。沉取之属阴。中得之为胃气。故无胃气则死。
左寸外以候心。内以候膻中。（其穴在两乳间）左关外以候肝。内以候膈中。左尺外以候
肾。内以候腹中（腹属下焦。右手尺中亦可候也。）
右寸外以候肺。内以候胸中。（三焦之所主也）右关外以候脾。内以候胃脘。右尺外以候
心主。内以候腰。

The Cun position corresponds to Heaven. It governs the Upper Jiao (Upper Burner). Its diagnostic scope covers diseases from below the head down to the Heart. The Guan position corresponds to Humanity. It governs the Middle Jiao (Middle Burner). Its diagnostic scope covers diseases from below the Heart down to the umbilicus. The Chi position corresponds to Earth. It governs the Lower Jiao (Lower Burner). Its diagnostic scope covers diseases from below the umbilicus down to the feet.
The Three Positions refer to the Upper, Middle, and Lower sections, which are the Cun, Guan, and Chi positions respectively. Each position has three grades of pressure (Floating, Middle, Deep), each corresponding to Heaven, Humanity, and Earth. The Heaven grade of the Upper section is used to inspect the head and temples; the Humanity grade of the Upper section is used to inspect the ears and eyes; the Earth grade of the Upper section is used to inspect the mouth and teeth. The Heaven grade of the Middle section is used to inspect the Lungs; the Humanity grade of the Middle section is used to inspect the Heart; the Earth grade of the Middle section is used to inspect the chest interior. The Heaven grade of the Lower section is used to inspect the Liver; the Humanity grade of the Lower section is used to inspect the Spleen and Stomach; the Earth grade of the Lower section is used to inspect the Kidneys. (Although there are several theories regarding the Nine Grades, this explanation is easier to understand, though it is difficult to apply in current practice; therefore, it is retained here for reference.)
Wang Ziheng stated: A single pulse position has three grades. Floating pressure belongs to Yang; deep pressure belongs to Yin; obtaining the pulse with moderate pressure indicates Stomach Qi. Therefore, if Stomach Qi is absent, death ensues.
The outer aspect of the Left Cun position is used to inspect the Heart; the inner aspect is used to inspect the Danzhong (Chest Center) [located between the two nipples]. The outer aspect of the Left Guan position is used to inspect the Liver; the inner aspect is used to inspect the Diaphragm center. The outer aspect of the Left Chi position is used to inspect the Kidneys; the inner aspect is used to inspect the Abdominal center (The abdomen belongs to the Lower Jiao, so the Right Chi position can also be used for inspection).
The outer aspect of the Right Cun position is used to inspect the Lungs; the inner aspect is used to inspect the Chest interior (This is the domain governed by the Sanjiao/Triple Burner). The outer aspect of the Right Guan position is used to inspect the Spleen; the inner aspect is used to inspect the Epigastrium. The outer aspect of the Right Chi position is used to inspect the Xin Zhu (Heart Master/Pericardium); the inner aspect is used to inspect the Waist.
Spring pulses are Xian (Wiry) [meaning straight and taut like a bowstring]. Summer pulses are Hong (Surging) [another term is Gou (Hook), meaning the pulse comes swiftly and departs slowly]. Autumn pulses are Fu (Floating) [another term is Mao (Hair), meaning light as a goose feather rising]. Winter pulses are Chen (Deep) [another term is Ying or Shi (Stone), meaning sunken].
In Spring, the Liver pulse is slightly Xian (Wiry) and long [other descriptions include wiry, fine, and long; wiry, long, and soft; or soft, weak, and long].
In Summer, the Heart pulse is Hong (Surging), large, and dispersed [other descriptions include floating, large, and dispersed; floating, surging, and ...; surging, slightly solid; floating, large, surging, and long; or surging, large, and long]. Lu Guang stated: These descriptions are incorrect; they describe the Small Intestine pulse.
During the four seasons, the Spleen pulse is Na Na (Graceful/Elegant) and Huan (Slow) [other descriptions include soft, large, and slow; or deep, soft, and long. It prospers for eighteen days each in the third, sixth, ninth, and twelfth lunar months].
In Autumn, the Lung pulse is Fu (Floating), Se (Choppy), and short [other descriptions include slightly choppy and short; or light, void, and floating].
In Winter, the Kidney pulse is Chen (Deep), Zhi (Sluggish), and Hua (Slippery) [other descriptions include deep, soft, and short; deep, tight, and solid; deep and fine; deep, solid, and slippery; or deep, soft, and slippery].
