This is the chart of a 7 years old boy who recently found out that his father is having an affair. To complicate the matter, the lady is now pregnant.
To a wood DM, the earth star represents his father, the water star represents his mother and the wood star represents his sibling. So, the ji and gui inside the chou represent his father and the lady respectively. In 2013, gui-si year, the gui is revealed and so the lady is made known.
The year pillar is considered as "outside". So, the jia, his sibling star, inside the hai is waiting to appear from the "outside". The jia will appear in 2014, jia-wu year. Can you determine the gender of the baby?
