长生 Chang Sheng - Life Phases

What are the 12 life phases (长生 Cháng Shēng)?

The life cycle of the five elements is already discussed in the five seasons. A more refined method to determine the strength of the elements, specifically the "Day Master" strength, is the Twelve-life-stage method (长生 Cháng Shēng). While the Five Seasons method only considers the four quadrants (each season equals 90 degrees) plus the last 18 days of the third month to determine the elemental strength, the 12 Life Phases method divides each season further and considers every single month in each season.

There are four (five) seasons and twelve months, hence twelve different stages. The Day Masters Element in any given month's season determines its life stage, vitality, and strength.

An analogy of human life stages is used to describe the stages and strength of the elements; therefore, the strength indicator is called 十二长生, "The twelve Chang-Shengs," also commonly known as the 12 Qi/phases of life.
