生年四化 · Shēng Nián Sì Huà · The chart's engine
生年四化 (Shēng Nián Sì Huà) = the Four Transformations of your birth year — the engine of the whole Flying-Star reading. It is fixed by your birth-year heavenly stem (年干): that stem turns four main stars to Lu, Quan, Ke, and Ji and brands them onto your chart for life. Every flying-star deduction starts from these four birth-marks — the Lu is your innate blessing, the Ji your fated attachment and the first 'cause' to read.
The Birth-Year Four Transformations are one set of transformations fixed by the heavenly stem of the year you were born (年干): Hua Lu, Hua Quan, Hua Ke, and Hua Ji, each landing on a main star. A person born in a 甲 year, for instance, gets Lian Zhen in Lu, Po Jun in Quan, Wu Qu in Ke, and Tai Yang in Ji — those four stars and the palaces they sit in are 'lit up' from the moment of birth and never change.
In Flying-Star, the birth-year set is the 体 (tǐ) — the substance, the unchanging tone you are born with — while the palace-stem flights covered later are the 用 (yòng), the situational mechanism. You always read substance first (birth-year), then function (flights).
In the Flying-Star register, each transformation has a distinct flavour. Learn these four words and you have learned the alphabet.
Innate benefit and good affinity. The palace your Lu falls in is the life area that flows most easily and carries the most blessing.
Innate capability and the urge to lead. Your Quan palace is where you bear the most weight, want the most control, and grow the most.
Innate reputation and benefactors. Your Ke palace is where a good name comes, helpful people appear, and things smooth out — gently, slowly.
Innate attachment and lesson — and the whole chart's 'cause'. Your Ji palace is what you hold onto hardest and the first place to read.
Because the Ji marks the one thing you truly care about and cannot put down — you 'forbid' it precisely because it matters. The palace holding your birth-year Ji is the heaviest, most energy-dense point of the whole chart; the fortune of everything else is often read relative to 'where the Ji is'. The first cut of a Flying-Star reading always lands on the birth-year Ji.
The maxim is blunt: 'Ji is the cause, Lu is the affinity, and the result lands where the Ji strikes.' The Ji names the cause, the Lu names the sweetness, and the palace the Ji opposes is often where the outcome settles. Grasp the birth-year Ji first and the whole causal chain has a starting point.
Both are Four Transformations, but they play different roles: one is the tone you are born with, the other a mechanism each palace fires. Layered together, they make the full chart.
Look up your birth-year heavenly stem in the ten-stem transformation table — the very same table the San He school uses (甲: Lian-Po-Wu-Yang; 乙: Ji-Liang-Zi-Yin; and so on). Only the reading differs: San He treats it as a fortune modifier, Flying-Star as a causal starting point to chase. The easy path is to cast a free chart, which marks where each of your birth-year Lu, Quan, Ke, and Ji lands.
The Qin-Tian four-transformation lineage takes the birth-year set as substance and palace-stem flights as function; the birth-year assignment follows the ten-stem table of 《紫微斗数全书》, while the Flying-Star line makes the birth-year Ji the first cause of every reading.
The assignment is identical — the same ten-stem table (甲: Lian-Po-Wu-Yang, etc.). What differs is the reading: San He treats them as fortune points, Flying-Star treats them as causal starting points, chasing the Ji and flying the palaces to deduce dynamic relationships.
This is 'Lu and Ji in one palace', a two-sided setup where blessing and burden lean on each other: that life area gives you the greatest sweetness and the deepest attachment at once. It is not simply good or bad — it depends which palace. In Wealth, for example, it often reads as 'gifted at earning yet gripped by money'.
It gives a lifelong streak of contending with yourself — deep, focused, unwilling to lose, but prone to self-exhaustion. It builds depth and resilience, yet asks you to learn self-kindness and not live as one endless exam.
Every year stem carries all four — Lu, Quan, Ke, and Ji — so none is ever missing. Your Ke may simply sit on an auxiliary star like Wen Chang or Wen Qu, or share a palace inconspicuously, but it is always there; a cast chart will mark it.
