Heavenly Talisman (Tianfu) refers to the situation where the Central Transport Qi (Zhongyun) is identical to the Si Tian Qi (Si Tian). Taiyi Tianfu implies a complete convergence of the Central Transport, Si Tian, and Year Branch. Suihui requires that the Year Branch must be located in one of the four cardinal directions (Zi, Wu, Mao, You), while it is also suitable for the four corner positions (Chen, Xu, Chou, Wei) to serve as Suihui. The determination of Tongtianfu and Tongsuihui relies on the Central Transport being identical to the Zai Quan Qi (Zai Quan); there is no need to doubt whether the year is Yin or Yang.

The *Liu Weizhi Dalun* states: In the year of Jiazi, the Heavenly Count for the first phase (Chu Zhi Qi) begins at the first stroke under the water clepsydra and ends at 87.5 strokes. This indicates that each year is divided into six phases, with each phase lasting sixty days and 87.5 strokes. For example, in the year of Jiazi, the first phase begins at the initial stroke of the Yin hour and ends at the fourth stroke of the Zi hour, transitioning into the second phase (Er Zhi Qi) after the Spring Equinox, which precisely matches this count. The remaining years follow this pattern.

The *Liu Weizhi Dalun* states: In the year of Yichou, the Heavenly Count for the first phase begins at the twenty-sixth stroke, referring to the twenty-sixth stroke after the Yin hour on the day of Great Cold. After sixty days and 87.5 strokes, it transitions to the second phase at the Spring Equinox solar term. The remaining phases follow this pattern.

In the year of Bingyin, the Heavenly Count for the first phase begins at the fifty-first stroke, referring to the fifty-first stroke after the Yin hour on the day of Great Cold. The situation is the same as mentioned previously.

In the year of Dingmao, the final phase ends at the hundredth stroke under the water clepsydra. This signifies that the cycle of Zi, Chou, Yin, and Mao years constitutes one full period, ending here. Upon reaching the first phase of the Wuchen year, it restarts from the first stroke under the water clepsydra, aligning with the Qi movement of the Jiazi year. Detailed meanings are found in the subsequent "Explanation of the Diagram of Three Harmonies Convergence."

The *Liu Weizhi Dalun* states: In the year of Jiazi, the Heavenly Count begins at the first stroke under the water clepsydra and ends at 87.5 strokes. This indicates starting south of the Gen trigram position, specifically at the first stroke of the Yin hour. Since Yin is the beginning of the yearly day, as stated in the *Lingshu: Wei Qi Xing Pian*, the standard is usually set by dawn (Pingdan). A full day and night consist of one hundred strokes, and the authority managing heavenly phenomena records time using water clocks, hence it is said to begin at the first stroke under the water clepsydra.

The convergence of Year Qi through the Three Harmonies (Sanhe) is illustrated as follows: In the year of Jiazi, the first phase begins at the first stroke under the water clepsydra and ends at the twenty-fifth stroke in the final phase, referred to as "Initial Six," indicating the sun has completed one circuit. In the year of Yichou, the first phase begins at the twenty-sixth stroke and ends at the fiftieth stroke in the final phase, referred to as "Six Two," indicating the sun has completed two circuits. In the year of Bingyin, the first phase begins at the fifty-first stroke and ends at the seventy-fifth stroke in the final phase, referred to as "Six Three," indicating the sun has completed three circuits. In the year of Dingmao, the first phase begins at the seventy-sixth stroke and ends at the hundredth stroke under the water clepsydra in the final phase, referred to as "Six Four," indicating the sun has completed four circuits. Four circuits constitute one Ji (a period of twelve years).

Subsequently, in the years of Wuchen and Ren Shen, the count restarts from the first stroke, consistent with the Jiazi year. Thus, the years of Shen, Zi, and Chen form a Sanhe convergence in terms of Year Qi. Thereafter, the years of Si and You are identical to the year of Chou; the years of Wu and Xu are identical to the year of Yin; and the years of Hai and Wei are identical to the year of Mao. Therefore, the groups Shen-Zi-Chen, Si-You-Chou, Yin-Wu-Xu, and Hai-Mao-Wei all share identical Year Qi patterns, hence they are called Sanhe. By analogy, the pattern of Qi counts over sixty years can be clearly understood at a glance.
