Hidden stems and their Ten Gods
A branch is more than its surface element. Wei 未 hides Ji 己, Ding 丁, Yi 乙; read against the Day Master Xin 辛 they give the Ten God relations below. Hidden stems are what element strength is actually judged on — counting only the four visible stems badly understates what the branches carry.

| Ding 丁 | Fire | Seven Killings |
| Yi 乙 | Wood | Indirect Wealth |

The day pillar is the only one read from itself — every Ten God in the year, month and hour pillars is defined relative to the Day Master Xin 辛. Two people born in the same year and month with different day stems therefore have completely different charts. In Xin Wei 辛未 the Day Master Xin 辛 is yin Metal and sits on Wei 未, which is Earth; the relation between them is branch produces the Day Master. This seat is classically read as the Day Master's immediate environment.
