Hidden stems and their Ten Gods
A branch is more than its surface element. Zi 子 hides Gui 癸; read against the Day Master Ren 壬 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.

Where Ren Zi 壬子 sits in a chart
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 Ren 壬. Two people born in the same year and month with different day stems therefore have completely different charts. In Ren Zi 壬子 the Day Master Ren 壬 is yang Water and sits on Zi 子, which is Water; the relation between them is the same element. This seat is classically read as the Day Master's immediate environment.
