this is like astrology and can be really complex. not only the year you born, but the month, the date, the hour can mean a lot. as we have this "elements" stuff to discrible your personality and fate. the five elements are metal, wood, water, fire and earth. we check the birth year, month, date and hour, each of them gives 2 elements, so there will be 8 in all. that's your birth chart. if those 8 contain all the 5 elements then you are "complete". if, for example, you don't have water in those 8 elements you got, your parents will -guess what? add the word "water" in your name to make you complete. or, find you a wife/husband whose chart contains too much water.
this kind of things don't always happen nowadays, but believe or not, that really works. like astrology works sometimes.
the 5 elements make a circle. metal comes from earth, water comes from metal(when metal melt), wood comes from water(like tree grows), fire comes from wood(buring), and earth comes from fire(ember).
in the other way round, water kills fire, fire kills metal(melt), metal kills wood(axe), wood kills earth and earth kills water.
but don't bother asking me which kind of element are you. we are all metal, ya know.
[in fact, i'm a water person, and don't have wood in my chart. that's why i have a wood person as my bf
