I got the first copy of Master Ghost Valley's book when I was 30. A friend found it in a used book store and thought I would love to read it. Well, I read the introduction and thought to myself, "How good can it be just using the year and hour stems to read the life of a person? It divides people into just 100 types. It may be better than reading the animal zodiac but that's it."
One day, when I read about the life of Gui Gu Zi 鬼谷子 I remembered this book and took it out. First I had to shake off the dust on it before opening the book. I turned naturally to the page that should give myself a reading. Then I was shocked. Of course there are some details that do not match my life but it provides some information that I do not want to but have to admit it is true.
The book does not explain how the results are derived from the input. I tried and am still trying to crack the code and had just a little bit of luck and this remains an unfinished project. It is also one of the reasons for the production of this ebook hoping that someone will take up the job of relating the mere info of the birth year and hour stems to the valuable information about the life of a person.
