Chapter One
Ten Day Masters 十日主
At the centre of every chart stands one of ten Day Masters — the stem of your day of birth, the element that stands for you. Meet all ten.
Which one is yours? Every card opens its full entry in BaZi World.
Chapter Two
The Ten Gods 十神
Nothing in a chart is read alone. Every other stem takes its meaning from its relationship to your Day Master — ten relationships, known for a thousand years as the Ten Gods.
