This book is for people who are interested in Four Pillar of Destiny. There are 60 combinations of relationship and you will be one of them. With over 300 examples covered in this book, you will learn how to use basic BaZi philosophy to describe your relationship or marriage. Disclose what type of spouse and relationship you are going to have and the compatibility between you and your potential partner. What you should prepare yourself for better relationships. Most of the findings in this book are my experience and there are many relationship problem cases. With explanation of the logic behind, you can apply the principles yourself which enable you to perform your own projection. A mini Ten Thousand Year calendar for 50 years is enclosed so that you can do the Western to Chinese birthday conversion instantly. (Full calendar will be coming.) There are several reasons that make ancient Chinese four pillars undermined for its power. First, most people find it is abstract and difficult to start with. In fact, some learners spend years only stay at the theoretical level but not practical. In contrast, some experts are able to tell what is going to happen next day in detail, sound miraculous. All leading BaZi becomes superstition to public. Many no longer believe in this ancient arts could tell life up and down. In order to help readers get the most out of this book, I create my own terms to demonstrate techniques used in BaZi. By reading different relationship combinations, readers can understand and keep track their connections with people. For easy and simple, this book mainly looks at the third pillars, day pillar, without looking into Ten Stars (They are derived from interactions of positive-negative of Five Elements between the day-stem and the rest of the elements in BaZi chart) and lucky phase. (A pair of stem and branch comes in every 10 years or yearly to impact BaZi chart) Are you ready? In the coming next chapter, I will explain all the fundamental terms and logic you need to know before exploring this book.
