有气策加之。
阳年为太过年，阴年为不及年。子、寅、辰、午、申、戌，属阳年，丑、卯、巳、未、酉、
亥，皆阴年。主客皆自大寒日交司。天气为客之气也，客气交者后，有气策累加之，见六气所交日辰者也。

演纪上元自大唐麟德元年正月一日己酉朔，至大金明昌四年岁次癸丑，积得五百三十岁减一
算，以五百二十九年乘周天度三百六十五度二十四分三十六秒，乘之得一十九万三千二百一十三
日八十六分四十四秒。减交司差一十四日六十一分单九，外有一十九万三千一百九十九日二十五
分四十三秒奇一单九。（八十分以上，收为一日。）以天纪六十除之，外有五十九日二十五分四十三
秒奇一，命己酉。算外得戊申日大寒，乃交司日辰及分，乃壬寅年十二月中气大寒，交得癸丑，
司天气也。
到者司天进四地，阴阳上下定灾危，后学医流如晓得，逐年病体见根机。
假令癸丑年，太阴湿土司天，前四位，太阳寒水，司地。
逐年退三是客乡，上行实所上临方，初终六气轮排取，主客胜衰定者伤。
假令癸丑年，司天后三辰，亥是也，厥阴风木，为初之气，客也。子少阴君火，二之气，丑
太阴湿土，三之气，寅少阳相火，四之气，卯阳明燥金，五之气，辰太阳寒水，终之气。
有气策叠加推算。
阳年为太过之年，阴年为不及之年。子、寅、辰、午、申、戌年，属于阳年；丑、卯、巳、未、酉、亥年，都属于阴年。主气和客气都从大寒日开始交接主持。天气是指客行之气，客气交接之后，有气策累加推算，显示出六气所交接的日期和时辰。

演纪上元自大唐麟德元年正月一日己酉日初一（朔），到大金明昌四年岁次癸丑年，累计得到五百三十岁减去一算，以五百二十九年乘以周天度三百六十五度二十四分三十六秒，相乘得到一十九万三千二百一十三日八十六分四十四秒。减去交接时刻的差值一十四日六十一分单九，余下一十九万三千一百九十九日二十五分四十三秒奇一单九。（八十分以上，收进为一日。）用天纪六十去除它，余下五十九日二十五分四十三秒奇一，对应干支己酉。计算结束后得到戊申日的大寒节气，这就是交接主持的日期时辰及分数，这是壬寅年十二月中的中气大寒，交接得到癸丑年，由司天之气主持。
到任的司天之气前进四位在地支，阴阳上下确定灾祸与危险，后学医人如果懂得这个，逐年病证就能见到根本机理。
假设是癸丑年，太阴湿土司天，前四位是太阳寒水，在地在支。
逐年后退三位是客气的方位，上行实际到达的地方，初终六气轮流排布选取，主客胜衰决定谁受伤。
假设是癸丑年，司天后三辰，即亥位，是厥阴风木，作为初之气，属于客气。子位少阴君火，为二之气；丑位太阴湿土，为三之气；寅位少阳相火，为四之气；卯位阳明燥金，为五之气；辰位太阳寒水，为终之气。
There is the superposition of Qi Ce (astronomical calculation method for Qi).
Yang years are "Tai Guo" (Excess) years, and Yin years are "Bu Ji" (Deficiency) years. Zi, Yin, Chen, Wu, Shen, Xu belong to Yang years; Chou, Mao, Si, Wei, You, Hai all belong to Yin years. Both Zhu Qi (Host Qi) and Ke Qi (Guest Qi) begin their transition at Da Han (Major Cold). Tian Qi refers to the Guest Qi. After the transition of Guest Qi, there is cumulative addition via Qi Ce, revealing the dates and earthly branches when the Six Qi (Six Stages of Qi) transition.

From the First Year of Lin De era of Great Tang, January 1st, Jiyou day (New Moon), to the Gui Chou year of the fourth year of Mingchang era of Great Jin, a total of five hundred thirty years minus one calculation unit is accumulated. Multiplying five hundred twenty-nine years by the celestial degree of three hundred sixty-five degrees, twenty-four minutes, and thirty-six seconds yields one hundred ninety-three thousand two hundred thirteen days, eighty-six minutes, and forty-four seconds. Subtracting the transition difference of fourteen days, sixty-one minutes, and single nine, there remain one hundred ninety-three thousand one hundred ninety-nine days, twenty-five minutes, and forty-three seconds plus a remainder of single nine. (Eighty minutes or more are rounded up as one day.) Dividing by the Heavenly Cycle of sixty leaves fifty-nine days, twenty-five minutes, and forty-three seconds plus a remainder. This corresponds to Jiyou. Calculating outward yields the Da Han (Major Cold) solar term on Wushen day, which is the date, time, and fraction of the transition. This is the Major Cold mid-climate in the twelfth month of Renyin year, transitioning into Guichou year, where the Si Tian (Heavenly Ruler) Qi presides.
The arriving Si Tian (Heavenly Ruler) Qi advances four positions in the Earthly Branches; Yin-Yang above and below determine disaster and danger. If medical students understand this, they can see the root mechanism of diseases year by year.
For example, in the Guichou year, Taiyin Shitu (Great Yin Damp-Earth) is the Si Tian (Heavenly Ruler) Qi. The previous four positions correspond to Taiyang Hanshui (Great Yang Cold-Water), which governs the Di Zhi (Earthly Position).
Retreating three positions annually indicates the direction of the Guest Qi; it ascends to actually arrive at the specific location. The initial and final Six Qi (Six Stages of Qi) are taken by rotating sequence; the victory or decline of Host and Guest determines who suffers injury.
For example, in the Guichou year, three earthly branches after the Si Tian (Heavenly Ruler) is Hai. Jueyin Fengmu (Jueyin Wind-Wood) serves as the Chu Zhi Qi (Initial Qi), which is the Guest Qi. Zi position Shaoyin Junhuo (Shaoyin Ministerial Fire) is the Er Zhi Qi (Second Qi); Chou position Taiyin Shitu (Great Yin Damp-Earth) is the San Zhi Qi (Third Qi); Yin position Shaoyang Xianghuo (Shaoyang Ministerial Fire) is the Si Zhi Qi (Fourth Qi); Mao position Yangming Zaojin (Yangming Dry-Metal) is the Wu Zhi Qi (Fifth Qi); Chen position Taiyang Hanshui (Great Yang Cold-Water) is the Zhong Zhi Qi (Final Qi).
