不应者，沉细之脉也。甚至极沉极细，几于不可见矣；第
覆病者之手而诊之则见。凡值此不应之脉，乃岁运合宜，命曰
天和之脉，不必求治。若误治之，反伐天和矣。
土运为南政。盖土位居中，面南行令故也。金木水火四运，皆以臣事之，北面受令，故为北政。
甲己二年，为土运南政。（南政之年，南面行令，故其气在南，所以南为上而北为下，故寸为上而尺
为下，司天在上，在泉在下，人气应之，左右皆同。脉有不应者，谓阴之所在，脉乃沉细不应本脉也。
阴者，言六气有三阴三阳，而三阴之位，则少阴居中，太阴居左，厥阴居右。脉之不
应，乃以三阴之中而以少阴所居之处言之，又分南北二政，定其上下也。如遇少
阴司天，则两寸不应。厥阴司天，则右寸不应。太阴司天，则左寸不应。如少阴在泉，则两尺不应。
厥阴在泉，则右尺不应。太阴在泉，则左尺不应。）
乙丙丁戊庚辛壬癸八年，皆为北政。（北政之年，北面受令，其气在北，所以北为上而南为下，在
泉应上，司天应下，人气亦应之，故尺应下而寸应上。如遇少阴司天，则两尺不

当浮大而反沉细，寸当不应而反浮大，尺当浮大而反沉细，是为尺寸反。经曰∶“尺
寸反者死。”如右当不应而反浮大，左当浮大而反沉细，左当不应
而反浮大，右当浮大而反沉细，是谓左右交。经曰“左右交者死。”）
The "non-responsive" pulse refers to a deep and fine pulse. It may be extremely deep and extremely fine, almost imperceptible; however, it becomes palpable when the patient's hand is turned over for examination. Whenever such a non-responsive pulse is encountered, it indicates that the annual climate cycle is harmonious, known as the "Pulse of Heavenly Harmony," and no treatment is required. Erroneous treatment would instead damage this Heavenly Harmony.
The Earth phase belongs to Southern Governance. This is because Earth resides in the center and issues commands facing south. The Metal, Wood, Water, and Fire phases all serve it as ministers, receiving commands facing north, thus they are referred to as Northern Governance.
The years of Jia and Ji belong to Earth phase with Southern Governance. (In years of Southern Governance, commands are issued facing south, so the Qi is in the South; therefore, South is superior and North is inferior, making the Cun position superior and the Chi position inferior. The Si Tian [Heavenly Sovereign] Qi is above, and the Zai Quan [Earthly Ruler] Qi is below. Human Qi responds accordingly, with the left and right sides being identical. The term "pulse has non-responsiveness" means that where Yin Qi resides, the pulse becomes deep and fine, failing to reflect its normal character. By "Yin Qi," we refer to the Six Qi having three Yin and three Yang phases. Among the positions of the three Yin phases, Shao Yin [Lesser Yin] occupies the center, Tai Yin [Greater Yin] is on the left, and Jue Yin [Terminal Yin] is on the right. The concept of pulse non-responsiveness is discussed regarding the position occupied by Shao Yin among the three Yin phases, further divided into Southern and Northern Governance to determine superiority and inferiority. If Shao Yin is Si Tian, both Cun positions are non-responsive. If Jue Yin is Si Tian, the right Cun position is non-responsive. If Tai Yin is Si Tian, the left Cun position is non-responsive. If Shao Yin is Zai Quan, both Chi positions are non-responsive. If Jue Yin is Zai Quan, the right Chi position is non-responsive. If Tai Yin is Zai Quan, the left Chi position is non-responsive.)
The eight years of Yi, Bing, Ding, Wu, Geng, Xin, Ren, and Gui all belong to Northern Governance. (In years of Northern Governance, commands are received facing north, so the Qi is in the North; therefore, North is superior and South is inferior. The Zai Quan Qi corresponds to the upper part, and the Si Tian Qi corresponds to the lower part. Human Qi also responds accordingly, so the Chi position corresponds to the lower part and the Cun position to the upper part. If Shao Yin is Si Tian, both Chi positions are non-responsive. If Jue Yin is Si Tian, the right Chi position is non-responsive. If Tai Yin is Si Tian, the left Chi position is non-responsive. If Shao Yin is Zai Quan, both Cun positions are non-responsive. If Jue Yin is Zai Quan, the right Cun position is non-responsive. If Tai Yin is Zai Quan, the left Cun position is non-responsive. If the Chi position should be non-responsive but is instead floating and large, or if the Cun position should be floating and large but is instead deep and fine; or if the Cun position should be non-responsive but is instead floating and large, or if the Chi position should be floating and large but is instead deep and fine, this is termed "Reversal of Cun and Chi." The Classic states: "Death occurs with Reversal of Cun and Chi." If the right side should be non-responsive but is instead floating and large, or if the left side should be floating and large but is instead deep and fine; or if the left side should be non-responsive but is instead floating and large, or if the right side should be floating and large but is instead deep and fine, this is termed "Crossing of Left and Right." The Classic states: "Death occurs with Crossing of Left and Right.")
