The Ti and Yong Trigrams: Get This Foundation Right First
When using Plum Blossom Numerology (Meihua Yishu) to assess a move, many people stare at their Ti (body/self) and Yong (use/event) trigrams after casting and have no idea which is stronger, which is weaker, or who is generating or controlling whom. Before getting into "Bi He" and "Ti Sheng Yong," you need to be clear on the framework itself.
In Plum Blossom Numerology (Meihua Yishu), a cast produces a ben gua (original hexagram) and a bian gua (transformed hexagram). Within the ben gua, the single trigram that contains the moving line is called the Yong trigram — it represents the matter being asked about. The single trigram without the moving line is the Ti trigram — it represents the person asking. Applied to a relocation reading: the Ti trigram is you, and the Yong trigram is the move itself or the new dwelling. The Five Elements (Wu Xing) relationship between the two is the core thread running through the entire reading.
The casting method typically uses time numbers or observed object imagery to determine the upper and lower trigrams, then fixes the moving line. The details vary slightly across different lineages, but the logic for dividing Ti and Yong stays consistent.
What "Ti Yong Bi He" Means
"Bi He" means the Ti trigram and Yong trigram share the same Five Elements (Wu Xing) attribute. For example, if Ti is Zhen (thunder, Wood) and Yong is Xun (wind, Wood), both belong to Wood — that is Bi He.
In Plum Blossom Numerology (Meihua Yishu), Bi He is considered an auspicious pattern. The core logic is that energies of the same type naturally align; there is no clash or control, and both are pointed in the same direction. In the context of a relocation reading, the traditional interpretation is: this move fits your current state fairly well, resistance will be minimal, and after the move the person and the environment will be on a similar wavelength — the adjustment period should be relatively smooth.
That said, Bi He has a detail that is easy to overlook: Bi He means "not bad" — it does not equal "greatly auspicious." It tells you the direction is fine, but the force is not strong. If you want to judge whether fortune will noticeably improve after the move, Bi He alone is not enough. You also need to assess whether the Yong trigram is flourishing or weakened (wang/shuai), check the hu gua (nuclear hexagram), and see whether the bian gua adds stronger signals on top.
Another point: sometimes Ti and Yong appear to share the same Five Elements (Wu Xing) attribute on the surface, but one sits in a flourishing or prospering position while the other is at rest or imprisoned. In that case the Bi He is much weaker and cannot simply be classified as auspicious. This is the most common blind spot for beginners.
"Ti Sheng Yong" Is a Different Matter Entirely
Ti Sheng Yong means the Five Elements (Wu Xing) of the Ti trigram generates the Yong trigram. For example, if Ti is Li (fire, Fire) and Yong is Kun (earth, Earth), Fire generates Earth — that is Ti Sheng Yong.
The traditional explanation is that the person asking is expending their own energy and resources to drive the matter forward; the event itself receives nourishment, but the querent bears a cost. Applied to a move, the implication is roughly this: the relocation can happen, the new home or new environment will gradually improve, but you yourself will have to pay a considerable price — possibly money, energy, or time.
There is a common misunderstanding here: many people see the word "sheng" (generate/nourish) and assume it is positive. But Ti Sheng Yong and Yong Sheng Ti are actually reversed in terms of auspiciousness. Yong Sheng Ti is the more favorable pattern for the querent — it means the external environment nourishes and supports you. Ti Sheng Yong means you are outputting outward; from the querent's perspective this is a draining state.
For a relocation reading showing Ti Sheng Yong, my reading is: the move can proceed, but prepare mentally for budget overruns and a demanding early phase — do not expect things to feel easy the moment you arrive. Over the medium to long term, if the bian gua and hu gua carry no seriously negative signals, the outcome is usually acceptable.
A Few Key Points for Actual Readings
For questions about relocation, the Ti-Yong relationship is only the entry point. Getting a precise reading requires going several layers deeper.
First, assess the strength of the Yong trigram. The Yong trigram represents the move itself. If the Yong trigram is at rest or imprisoned, even a Bi He pattern means the matter will drag — possibly delayed again and again, or the new dwelling may carry hidden issues.
Second, examine the bian gua. The bian gua shows the ultimate direction of events. Sometimes the ben gua Ti-Yong relationship looks favorable, but the bian gua controls Ti — meaning a smooth start with problems developing later. That calls for caution.
Third, look at the hu gua. The hu gua is formed by the 2nd-3rd-4th and 3rd-4th-5th lines of the ben gua, giving two inner trigrams. It reflects the middle stage of how things unfold. From decision to move-in, there are many steps; the hu gua often reveals whether negotiations, renovations, or the transition period will run into trouble.
Fourth, pay attention to the moving line. The Five Elements (Wu Xing) attribute and position of the moving line directly affect the balance of power between Ti and Yong. If the moving line controls Ti, even when the overall pattern is not bad, watch for trouble at a specific node in the process.
People sometimes ask: if you have both Bi He and Yong Sheng Ti, is that the ideal pattern? Broadly speaking, yes — but hexagrams carry no fixed image. You still need to factor in the current season and the specific lines, and you cannot draw conclusions from two keywords alone. The essence of Plum Blossom Numerology (Meihua Yishu) lies in flexibility. Memorizing a handful of fixed conclusions tends to produce errors rather than accuracy.
