For male persons:

Use the count start 1 if your age is less than 13, 13 if your age is less than or 25, 25, 37, 49, 61, 73, 85, 97, 109
E.g. a male person age born in a Water Horse year with an age of 60.
Start counting from the Tiger with the count 49 and you find the sign Ox at the count of 60.
Now to find the element take the child of the child, etc. starting from the birth element using the aforementioned sequence.
So the child of Water is Wood at 1, Fire 13, Earth 25, Metal 37, Water 49 and as the next step 61 passes the age continue from this point with normal counting Water 50, Wood 51, Wood 52, Fire 53, Fire, 54, Earth 55, Earth 56, Metal 57, Metal 58, Water 59 and Water 60.
The found logmen is Water Ox.

Use the count start 1 if your age is less than 13, 13 if your age is less than 25, or 25, 37, 49, 61, 73, 85, 97, 109
E.g. a female person born in a Metal Tiger year with an age of 52.
Start counting from the Monkey with 49 and you find the sign Snake at the count of 52.
To find the element take the mother of the mother, etc.
So the mother of Metal is Earth at 1, Fire 13, Wood 25, Water 37, Metal 49, as and as the next step 61 passes the age do not continue with Metal, but continue with the next element Earth 50, Earth 51, Fire 52.
