必先将其人岁数之零数，从今年天干起，逆推至若干位，即以其干，为生年天干。（岁数若为整十无零，则作十数论）例如三十七岁，七为零数，今年癸酉，自癸至丁，逆数是得七位（癸一壬二辛三庚四己五戊六丁七）即知所生之年，天干值丁。

結果 (英文) 2:

It must first zero number of people age, this year from Heavenly, backstepping to a number of bits, with its dry, living in Heavenly. (Age if the entire ten non zero, then make a dozen theory) such as thirty-year-old, seven zero number, year GuiYou, since decanoate to Ding, the inverse number is obtained seven (decanoate a azelaic Xin Sangeng four had five pent-six Ding seven) that is known born of years, Ding Heavenly value.

結果 (英文) 3:

Before going to zero by age, from this day onwards, the inverse push to several, in the dry, for years. (age if for ten whole without zero for ten) such as 37 years old, seven is zero, this Guiyou, decyl to Ding, inverse number is seven (six five capric Ren Xin Sangeng four has e d 7) that is known to the years, heavenly value Ding.
