Both husband and wife are fortune tellers. The man has a son and the woman doesn't know how to solve it.

Fortune-telling is to expel people from the date of birth according to their date of birth, and to infer good or bad luck. We can't help asking, how many people were born at the same time in the country? China has a population of 654.38+03 billion, and there are only over 500,000 kinds of eight characters, with an average of 3,000 people per character. Is the fate of these three thousand people the same? Obviously impossible. So don't trust fortune tellers. Husband and wife tell fortune. The man has a son and the woman doesn't. It only means that the fortune teller is talking nonsense. You don't have to tell fortune, even if you forget, you can solve the problem.
