as far as i know, 8 mansion use a person Gua number which is derive from a person year of birth and let say a female was born in april 1996, autromatically her Gua number is 2, and let say her dad Gua is number 6
The year now is 2010, so how do we derive the Gua number for each person ? will the 2010 also different use in male and female ?
