间气（客气中位于司天和在泉两侧的六步之气）的设置，是逐年轮转运行的，这原本是就客气而言的；至于主气（每年固定不变的六步之气），则上下左右的位置都是固定不变、不会移动的。

总结规律：司天之气对应第三步气，在泉之气对应第六步气（终气）；司天的左间气对应第四步气，右间气对应第二步气；在泉的右间气对应第五步气，左间气对应第六步气（注：此处原文“左间为终气”似有笔误或特定语境，通常司天在泉相对，左间右间位置固定，依前文逻辑，在泉左间应为终气之前的步骤或特定对应，但此处忠实翻译原文表述）。
The arrangement of the Intermittent Qi (Jian Qi, the six steps of the Transient Qi located on either side of the ruling Qi and the commanding Qi) rotates year by year; this description originally refers to the Transient Qi. As for the Principal Qi (Zhu Qi, the six fixed steps of Qi that remain constant throughout the year), their positions above, below, left, and right are fixed and unchanging.
In years of Zi and Wu: The Sovereign Fire (Jun Huo, referring to Shaoyin or Shaoyang depending on context, here specifically linked to the ruling position in the subsequent explanation of other years' structures, but traditionally Zi/Wu is Shaoyin Jun Huo Si Tian) rules from above (Si Tian). In years of Mao and You, Dryness Metal (Zao Jin) commands from below (Zai Quan); in years of Yin and Shen, Ministerial Fire (Xiang Huo, Shaoyang) serves as the Right Intermittent Qi of the commanding Qi; in years of Chen and Xu, Cold Water (Han Shui, Taiyang) serves as the Left Intermittent Qi of the commanding Qi; in years of Chou and Wei, Damp Earth (Shi Tu, Taiyin) serves as the Left Intermittent Qi of the ruling Qi; in years of Si and Hai, Wind Wood (Feng Mu, Jueyin) serves as the Right Intermittent Qi of the ruling Qi.
During the years of Zi and Wu: The First Qi is Taiyang (Greater Yang/Cold Water), the Second Qi is Jueyin (Wind Wood), the Third Qi is Shaoyin (Sovereign Fire), the Fourth Qi is Taiyin (Damp Earth), the Fifth Qi is Shaoyang (Ministerial Fire), and the Final Qi is Yangming (Dryness Metal).

During the years of Mao and You: The First Qi is Taiyin (Damp Earth), the Second Qi is Shaoyang (Ministerial Fire), the Third Qi is Yangming (Dryness Metal), the Fourth Qi is Taiyang (Cold Water), the Fifth Qi is Jueyin (Wind Wood), and the Final Qi is Shaoyin (Sovereign Fire).

In years of Si and Hai: Wind Wood (Jueyin) rules from above (Si Tian); in years of Yin and Shen, Ministerial Fire (Xiang Huo) commands from below (Zai Quan); in years of Chou and Wei, Damp Earth (Shi Tu) serves as the Right Intermittent Qi of the commanding Qi; in years of Mao and You, Dryness Metal (Zao Jin) serves as the Left Intermittent Qi of the commanding Qi; in years of Zi and Wu, Sovereign Fire (Jun Huo) serves as the Left Intermittent Qi of the ruling Qi; in years of Chen and Xu, Cold Water (Han Shui) serves as the Right Intermittent Qi of the ruling Qi.
During the years of Si and Hai: The First Qi is Yangming (Dryness Metal), the Second Qi is Taiyang (Cold Water), the Third Qi is Jueyin (Wind Wood), the Fourth Qi is Shaoyin (Sovereign Fire), the Fifth Qi is Taiyin (Damp Earth), and the Final Qi is Shaoyang (Ministerial Fire).
In years of Chou and Wei: Damp Earth (Taiyin) rules from above (Si Tian); in years of Chen and Xu, Cold Water (Han Shui) commands from below (Zai Quan); in years of Mao and You, Dryness Metal (Zao Jin) serves as the Right Intermittent Qi of the commanding Qi; in years of Si and Hai, Wind Wood (Feng Mu) serves as the Left Intermittent Qi of the commanding Qi; in years of Yin and Shen, Ministerial Fire (Xiang Huo) serves as the Left Intermittent Qi of the ruling Qi; in years of Zi and Wu, Sovereign Fire (Jun Huo) serves as the Right Intermittent Qi of the ruling Qi.
During the years of Chou and Wei: The First Qi is Jueyin (Wind Wood), the Second Qi is Shaoyin (Sovereign Fire), the Third Qi is Taiyin (Damp Earth), the Fourth Qi is Shaoyang (Ministerial Fire), the Fifth Qi is Yangming (Dryness Metal), and the Final Qi is Taiyang (Cold Water).
In years of Chen and Xu: Cold Water (Taiyang) rules from above (Si Tian); in years of Chou and Wei, Damp Earth (Shi Tu) commands from below (Zai Quan); in years of Zi and Wu, Sovereign Fire (Jun Huo) serves as the Right Intermittent Qi of the commanding Qi; in years of Yin and Shen, Ministerial Fire (Xiang Huo) serves as the Left Intermittent Qi of the commanding Qi; in years of Si and Hai, Wind Wood (Feng Mu) serves as the Left Intermittent Qi of the ruling Qi; in years of Mao and You, Dryness Metal (Zao Jin) serves as the Right Intermittent Qi of the ruling Qi.

To summarize the pattern: The Ruling Qi (Si Tian) corresponds to the Third Qi; the Commanding Qi (Zai Quan) corresponds to the Final Qi (Sixth Qi); the Left Intermittent Qi of the Ruling Qi corresponds to the Fourth Qi, and its Right Intermittent Qi corresponds to the Second Qi; the Right Intermittent Qi of the Commanding Qi corresponds to the Fifth Qi, and the Left Intermittent Qi corresponds to the Final Qi (Note: The original text states "Left Intermittent [of Zai Quan] is Final Qi," which may contain a textual error or specific contextual logic, as typically the Final Qi is Zai Quan itself or follows a specific sequence; however, the translation faithfully renders the source text).
