How Da Yun and Liu Nian Divide the Work
Da Yun rules the decade, Liu Nian rules the year
Da Yun works on a ten-year cycle and sets long-term trends. Liu Nian works on a one-year cycle and pins down when events land. The two are not peers — one frames, one triggers. Da Yun draws the decade's theme; Liu Nian pulls the trigger in the right year. To time any event, fix the Da Yun frame first, then find the Liu Nian trigger inside it.
Da Yun sets the direction, Liu Nian sets the timing. Aligned, they amplify. Opposed, they cancel. In practice, first see which Da Yun you're in, then check whether this year's Liu Nian strengthens or weakens it.
Four Dimensions of the Interaction
Career & Wealth
A wealth Da Yun makes money the decade's main line; the year money lands depends on the Liu Nian stirring the wealth star. A career Da Yun makes job changes the main line; the promotion year depends on the Liu Nian stirring the officer star. When Da Yun and Liu Nian are both favorable, you've found the decade's strongest window to act.
Love & Relationship
For men, a wealth Da Yun; for women, an officer Da Yun — marriage and romance become the decade's main line. A Liu Nian that brings the spouse star as a favorable element marks a high-probability year for dating, romance, or marriage. When a Liu Nian clashes or combines the marriage palace, married partners can expect shifts.
Personality
Da Yun shapes character at the base level, over the long run. Liu Nian shapes it at the event level, within the year. To read a person's phase-of-life temperament, check Da Yun first, then Liu Nian.
Health
In an unfavorable Da Yun, constitution declines year by year. The Liu Nian that feeds the unfavorable element is when health problems cluster. Plan long-term routines by Da Yun; dodge the high-risk months by Liu Nian.

How to Use Them Together
- Fix the Da Yun first, then read the Liu Nian: To read a year, first ask which Da Yun you're in — wealth, career, or unfavorable. Then check whether this year's Liu Nian strengthens or weakens that theme.
- When they align, act decisively: When Da Yun and Liu Nian point the same way and both favor you, that's the decade's best window to act. Put big moves in those years.
- When they oppose, downshift and steady: Good Da Yun, bad Liu Nian — play it safe this year and wait. Bad Da Yun, good Liu Nian — test small, don't bet big. When the big trend is off, even good timing doesn't earn an all-in.
Common Questions
Q:Which matters more, Da Yun or Liu Nian?
A:
You can't rank them simply. Da Yun is more basic — it sets the decade's direction. Liu Nian is more specific — it sets this year's events. In an unfavorable decade, a good Liu Nian is just a bright spot. In a favorable decade, a bad Liu Nian is just a passing shower. Read Da Yun for the character, then Liu Nian for the point.
Q:What happens when Da Yun and Liu Nian oppose?
A:
They cancel out. Good Da Yun, bad Liu Nian — this year's chances get held down. Bad Da Yun, good Liu Nian — a small bounce this year, but the big trend holds. Judge by the net effect after the offset.
Q:What does Sui Yun Bing Lin mean?
A:

Q:How do I tell if Da Yun and Liu Nian align?
A:
Check whether both stem-branch pairs push your day master the same way. Both supporting your favorable elements, or both suppressing the unfavorable — that's aligned; otherwise they oppose. Same-polarity pairs strike harder, so the contrast runs clearer.
