Direct answer
Da Yun adds sequential ten-year stem-and-branch contexts to the natal chart. It changes which relationships are emphasized, but it does not erase the natal structure or guarantee an event.
Read it in this order
Verify gender-based direction under the selected traditional rule, the start date derived from solar-term distance, and the exact civil or true-solar birth time. Compare the current and next cycle before adding an annual pillar.
From symbol to real life
Use the current decade to define the chapter, the annual pillar to define the planning question, and shorter timing only for experiments or reviews. Do not choose an irreversible date from timing alone.

This method cannot guarantee wealth, health, legal, work, or relationship outcomes. It is for cultural reflection and planning questions; major decisions still require real evidence and qualified advice.
FAQ
Does a new Da Yun change life overnight?
Usually not. A Da Yun is a ten-year context whose themes can become visible gradually and through real circumstances. The start date is a calculation boundary, not a guarantee that life changes overnight.
How does Ziheng handle disputed judgement?
Balance, climate, and structure evidence stay separate; a primary direction appears only when at least two lenses agree.
