More then just Year.

There is a time difference in the year your born   months are not the same back in 1990 as they are today on the calendar.  the days or months move up and down.

===========================================

To understand the truth meaning of the five elements and the 4 pillars of destiny, I recommend that you also learned the second set of magic number, Ha Do .

When I was your age, I also learned and read alot of books about feng shui and Chinese astrology. All of them talk about the first set of magic number, LacThu . But there is a book that discuss about the second set of magic number, Ha Do.  What I have describe the above information is just the beginning of the secret of past.

You are young and have alot of time to study or discover the hidden knowledge. 90% of the mystery of Chinese Fortune, Feng-Shui, Pa Kua, etc ... lies within the basic

- the ying/yang

- 5 elements: Water, Wood, Fire, Earth & Metal

- Lac Thu
4 .. 9 .. 2
3 .. 5 .. 7
8 .. 1 .. 6

- Ha Do
2 .. 7 .. 4
3 .. 5 .. 9
8 .. 1 .. 6

Good luck in your quest for knowledge
