The Climate Adjustment Yongshen Method 调候用神法: Balancing the Four Seasons in Bazi

When the Cold of Winter Stifles Growth: The Mandate of Climate Adjustment

A chart born in the depth of winter carries the austerity of ice — the 调候用神法 (Climate Adjustment Yongshen Method) judges that such a chart will achieve balance only if it receives the warmth of 🔥火. Unlike methods that focus on the strength of the day master, this approach looks first at the elemental climate of the birth season. It asks not "what does the day master need?" but "what does the season demand?" For a winter-born chart, even if fire is the day master's enemy element in conventional balancing, it may still become the lifesaving useful god because the cold must be dispelled before any other refinement can occur.

The Classical Definition of Tiaohou Yongshen

The 调候用神法 (Climate Adjustment Useful God method) draws directly from the classical text 《穷通宝鉴》 (Qiongtong Baojian), a treatise on the seasonal tendencies of the ten heavenly stems. The central premise is that each season imposes a climatic condition that either nourishes or suppresses the five elements. The method prescribes that the primary useful god (用神 yongshen) should be the element that moderates the extreme cold, heat, dryness, or dampness of the season. For example:

- Winter (亥, 子, 丑 months): Requires 🔥 fire (especially 丙午) to warm the frozen ground. - Summer (巳, 午, 未 months): Needs 💧 water (壬癸) to cool the scorching heat. - Spring (寅, 卯, 辰 months): If too wet from lingering winter, needs 🔥 fire and 🪨 earth; if too dry, needs 💧 water to nurture growth. - Autumn (申, 酉, 戌 months): Often dry, needing 💧 water for moisture; if early autumn retains summer heat, also needs 🔥 fire or 💧 water as appropriate.

The 用神 is not chosen based on the day master's personal preference in a vacuum, but on the season's overriding need. This is why the method is also called "climate adjustment" — it adjusts the chart's elemental temperature to a comfortable middle ground.

When to Use This Method vs Other Yongshen Methods

The Tiaohou method is most relevant when a chart exhibits a clear climatic imbalance. If a chart is born in the dead of winter (子月) with no 火 in the four pillars, or in the peak of summer (午月) with no 水, then the climate adjustment principle becomes the first priority. In such cases, other methods like 扶抑用神法 (the Support-Offset Method) or 通关用神法 (the Passage Method) may take a secondary role until the climate is balanced.

However, if the chart already contains sufficient moderating elements (e.g., a winter chart with a 午 branch or a 丙 stem), the climate may already be comfortable, and you can then shift to other methods. The Tiaohou method should never be applied in isolation — it works best as the initial filter before assessing day master strength and elemental interactions. For charts born in mild seasons like spring or autumn, the climate may already be moderate, and the Tiaohou method may yield a weaker influence compared to other factors.

Step-by-Step Walkthrough of the Tiaohou Method

To apply the Tiaohou Yongshen method, follow these five steps:

Step 1: Identify the Month of Birth

Determine the Chinese lunar month (地支 branch of the month pillar). Each month has a dominant climate: - 寅, 卯, 辰: Spring (warming, damp) - 巳, 午, 未: Summer (hot, dry) - 申, 酉, 戌: Autumn (cooling, dry) - 亥, 子, 丑: Winter (cold, damp)

Step 2: Assess the Extremity

Consider if the month is a peak of the season (子 or 午) or a transitional month (辰, 丑, 戌, 未). Peak months exert stronger climatic pressure. Also note the presence of other branches that reinforce or contradict the season (e.g., a 巳 month branch combined with 午 in year branch intensifies heat).

Step 3: Apply the Classical Heuristic

Consult the 《穷通宝鉴》 guidelines for each heavenly stem in each month. For example: - **甲木 in 子月:** The cold wood needs 丙火 (fire) and also 戊土 (earth) to control the water. The primary 用神 is 丙火. - **丙火 in 午月:** The hot fire needs 壬水 (water) and maybe 庚金 (metal) to generate water. The primary 用神 is 壬水.

These heuristics are not absolute rules but strong tendencies. They assume the chart lacks other strong counter-forces.

Step 4: Confirm with the Four Pillars

Check if the climatic corrective element actually appears in the chart. If it is present and moderately strong (not overly damaged), it becomes the 用神. If it is missing, the chart suffers from an extreme climate and the Tiaohou method indicates a deficiency that must be addressed in the person's life or by external factors.

Step 5: Adjust for Interactions

Consider 支合 (branch combinations) that can alter the climate. For example, 子丑合 can transform into 土, which might reduce cold. 巳酉丑合金 can bring metal, which might introduce cold if autumn. Adjust the climate assessment accordingly.

Worked Example: A Winter-Born Chart

Let us take a hypothetical chart for "Mr. Wang," born on 15 December 1990 (around the 子月). His four pillars are:

- Year: 庚午 - Month: 戊子 - Day: 甲子 - Hour: 丙寅

The day master is 甲木. The month is 子 (deep winter), and the day branch is also 子, doubling the cold. The year branch 午 provides some 🧯 fire, and the hour stem 丙 brings a sun-like warmth. However, the cold is still overwhelming.

Applying the Tiaohou method: 《穷通宝鉴》 says for 甲木 in 子月, the primary 用神 is 丙火 to warm the wood, with 戊土 as a secondary 喜神 (supporting god) to control water. In the chart, 丙火 appears in the hour stem, and 午火 in the year branch. But the 子 water (month and day) is too strong, drowning the 午火. The 丙火 is present but sits on 寅 (a wood branch), which slightly fuels it. Nevertheless, the climate is still very cold. Therefore, the Tiaohou method identifies 丙火 as the 用神, but since it is not strong enough to completely balance the cold, this person may need to seek proactive "fire" elements in their environment — career in creativity, fire-related industries, or living in warm climates. The 午火 in the year branch acts as a supporting god (喜神), but the 子水 remains a strong 忌神 (taboo god) that suppresses the warmth.

Common Pitfalls in Applying the Tiaohou Method

1. Ignoring the day master's own element needs: The climate may demand fire, but if the day master is 壬水 in winter, too much fire could create conflict. Always check the day master's personal needs after climate adjustment. 2. Overgeneralizing the season: Not every winter-born chart needs fire. If the chart has abundant 土, it may already block cold. Or if the chart includes 巳 (fire snake) in the hour, the cold might be mitigated. Apply the classical heuristics with caution. 3. Forgetting branch combinations: A 亥子丑 combination turns into full water, making cold extreme. Conversely, 寅午戌 combination adds fire. Always check for these before finalizing the 用神. 4. Confusing climate adjustment with day master support: The Tiaohou method is about the chart's comfort, not about making the day master strong. A 己土 (weak earth) day master in summer might need water for climate, but that water could weaken the earth further. You must then choose which priority to follow — often climate takes precedence unless it destroys the day master entirely.

How This Method Differs from Related Methods

The Tiaohou method is distinct from the 扶抑用神法 (Support-Offset Method), which aims to strengthen a weak day master or weaken a strong one. While the Support-Offset method looks at the internal dynamics of the five elements around the day master, the Tiaohou method looks at the external environment of the season. For example, a strong 火 day master in summer does not need Support-Offset, but still requires the Tiaohou adjustment of water to cool the chart. The two methods can conflict; the experienced practitioner must weigh both.

Similarly, the 通关用神法 (Passage Method) resolves elemental conflict (e.g., metal and wood fighting) by introducing a mediating element (e.g., water). The Tiaohou method does not care about conflict resolution as much as about temperature. A chart with metal and wood in winter may still need fire before considering passage. The Tiaohou method is often applied first because a chart cannot function properly if it is frozen or scorched.

One Line on Destiny and Pattern

No birth chart dictates an immutable fate; the Tiaohou method offers a perspective on how to navigate life's extremes, not a guarantee. It reminds us that balance comes from understanding our inherent climate and consciously seeking what is missing.

For a deeper exploration of your own chart's climate, consider generating a full Bazi chart to see the season's influence alongside other factors. To better understand how the 用神 interacts with the day master, read our guide on Yongshen selection methods, or learn about the heavenly stems and earthly branches that create the climatic conditions. The Tiaohou method is just one lens, but for many charts, it is the lens that brings the picture into focus.
