What does the imaginary yen mean in fortune telling?

"Japanese yen"-refers to one of the four pillars in the date of birth. Numerology says that "the yen is the mainstay" and "the day is the yuan god". "Lack of yen" means that at the moment of birth, you can't get help from similar factors in the five elements. In the twenty-four solar terms and in the twelfth house, you can't be timely. It can also mean that the similarity factors in your five elements are weak, that is, if the day you were born is dry, however, whether the yen is empty or prosperous, it depends on four pillars and eight favorite gods.
