How Ti Gua and Yong Gua Are Determined
When casting a hexagram with Plum Blossom Numerology (Meihua Yishu), the first task after obtaining the primary and transformed hexagrams is to identify which is the Ti Gua (Body Trigram) and which is the Yong Gua (Use Trigram). The rule is straightforward: the trigram containing the moving line is the Yong Gua, and the other is the Ti Gua. If the moving line falls in the upper trigram, the upper is Yong and the lower is Ti; if the moving line falls in the lower trigram, the lower is Yong and the upper is Ti. The Ti Gua represents the person asking the question, while the Yong Gua represents the subject or situation being asked about.
In relationship readings, that subject can be a specific person, a romantic connection, a collaborative project, or an employment relationship. Grounding the Yong Gua in something concrete gives the reading a real anchor.
The Five Elements (Wu Xing) logic then comes into play: each trigram carries a Five Elements (Wu Xing) attribute (Qian and Dui belong to Metal, Zhen and Xun to Wood, Kan to Water, Li to Fire, Gen and Kun to Earth). When an overcoming relationship exists between Ti and Yong, the key question is which direction that overcoming runs.
What Does Ti Ke Yong Mean?
Ti Ke Yong means the Ti Gua overcomes the Yong Gua. For example, if Ti Gua is Kan (Water) and Yong Gua is Li (Fire), Water overcomes Fire — this is a Ti Ke Yong configuration.
The basic reading here is that the querent holds the active, dominant position in the relationship, with the capacity to influence, suppress, or even control the other person or situation.
In romance, this typically means the querent is the more proactive partner and the other person is more reliant or accommodating. In collaboration, it means you hold stronger negotiating leverage. In competition, it suggests you have the upper hand.
But Ti Ke Yong does not equal a good outcome. Overcoming inherently carries a quality of drain and suppression — excessive control in a relationship can lead to possessiveness, the other party pulling away, or the relationship becoming exhausting. Traditional interpretation generally classifies Ti Ke Yong as "workable" (ke wei), meaning the matter can be pushed forward and you hold the initiative, but not that the process will be smooth or that the other party will cooperate willingly.
One point that is often overlooked: the strength (wang shuai) of the Ti Gua itself matters enormously. If the Ti Gua is in a weak or confined state (xiu qiu) relative to the current month's ruling element, then even with Ti Ke Yong, that overcoming is feeble — the actual capacity to influence is far weaker than it appears on the surface. So looking at the single overcoming relationship is never enough; you must factor in the seasonal and monthly context.
What Does Yong Ke Ti Mean?
Yong Ke Ti is the reverse: the Yong Gua overcomes the Ti Gua. Flipping the earlier example — Ti Gua is Li (Fire) and Yong Gua is Kan (Water), with Water overcoming Fire — gives you Yong Ke Ti.
The basic reading here is that the querent is in a passive, suppressed position. The subject or the other person holds stronger influence over you, and may even represent some form of threat or constraint.
In romance, Yong Ke Ti often appears when one party is clearly weaker in the dynamic — suppressing themselves to accommodate the other — or when the other person's attitude is causing the querent anxiety. In workplace dynamics, it frequently maps onto pressure from a superior or being at a disadvantage in peer competition. In collaboration, it signals that the initiative lies with the other side.
A folk saying in hexagram interpretation holds that Yong Ke Ti suggests being "controlled" (bei zhi) — in mild cases restricted, in severe cases harmed. That "harm" is not necessarily material; emotional drain and wounded self-esteem count just as well.
My own view is that Yong Ke Ti does not automatically mean a bad outcome, but it clearly signals that the querent currently lacks the initiative. If you are asking "can I push this relationship forward," the Yong Ke Ti answer is essentially: forcing it will be laborious and reactive — better to adjust your posture first.
Here too, the strength of the Yong Gua determines how heavy that overcoming really is. A strong Yong Gua means the pressure is real; a weak Yong Gua softens the configuration considerably — sometimes the other party is only superficially strong and is in fact bluffing.
What Else to Look at Beyond the Overcoming Relationship
Some practitioners, after learning the Ti-Yong overcoming framework, focus exclusively on that single relationship and neglect other key factors.
The Hu Gua (mutual hexagram) and Bian Gua (transformed hexagram) carry significant weight. The Hu Gua reflects the middle process of how things unfold; the Bian Gua reflects the ultimate direction. If Ti Ke Yong holds in the primary hexagram but the Bian Gua shows Yong Ke Ti, it means you are active now but the balance will flip over time. This kind of reversal is quite common in romance — the initial pursuer holds the lead, but as feelings deepen, the dependency quietly shifts direction.
Generating relationships also matter greatly in relationship readings. Ti Sheng Yong (Ti generates Yong) means you are actively giving and nurturing the other party — you are investing heavily in this relationship. Yong Sheng Ti (Yong generates Ti) means the other party is supporting and benefiting you. Many people feel happy when they see Yong Sheng Ti, interpreting it as "the other person loves me." That direction is reasonable, but always check whether the Yong Gua is in a strong state — a strong Yong Gua generating Ti is genuinely supportive; a weak one is not.
One more configuration worth addressing separately: Ti Yong Bi He, where Ti and Yong share the same Five Elements (Wu Xing) attribute and there is no overcoming relationship. Traditional readings describe this as the two parties being evenly matched, with limited mutual influence and weak initiative from either side. It reads reasonably well for collaboration but can feel flat in romance — lacking the push to move things forward.
Ti Ke Yong and Yong Ke Ti are the two most fundamental interpretive frameworks for Plum Blossom Numerology (Meihua Yishu) relationship readings. Once you have the direction clear, layering in strength analysis, the Hu Gua, the Bian Gua, and generating-combining details is what brings the reading into focus.
