Can fortune tellers have children?

Fortune-telling is the life of ordinary descendants, but it can't be accurate. At least tens of thousands of people were born at the same time on the same day of the same year. Is it the same fate? Impossible, it has something to do with birthplace and family environment. So there is no way to calculate accurately, let alone tell fortune. Even if the child comes, it will be effective to invite the child in the formal altar of Songzi Pavilion.
