How old is a good fortune teller _ how old is a good child?

I said/kloc-children under 0/4 should not tell fortune.

Newborn children can tell fortune. Why can't 14 be counted? Since ancient times, there are many children's customs. After the child is born, many parents will do the math to see what is wrong with the custom and what needs attention, such as bringing a bow and arrow. You can't go to the General Temple, watch the funeral, eat the funeral banquet, see the cemetery, see the coffin, and so on. Then you can see what the children lack in Jin Mu's five elements of fire and water, and what kind of words do you want to choose for the name, which is good for the eight characters. All newborns should be counted. Why can't 14 be counted?
