# The Four Transformations · 生年四化

The heavenly stem of the **birth year** turns four specific stars into the Four Transformations — Lu (fortune), Quan (power), Ke (fame) and Ji (obstacle). They are among the most important factors in interpreting a chart, marking where energy flows and where it snags.

## The four

- [化祿 (Huà Lù / Transformation of Fortune)](./lu.md) — resource, gain
- [化權 (Huà Quán / Transformation of Power)](./quan.md) — authority, drive
- [化科 (Huà Kē / Transformation of Fame)](./ke.md) — reputation, study
- [化忌 (Huà Jì / Transformation of Obstacle)](./ji.md) — attachment, loss
