What does this sentence mean? A man and a woman are unfit to be husband and wife. When disasters and diseases strike, the two will spread out and cry all day and all night.

In other words, men's wooden life and women's indigenous life will be mutually exclusive and should not be married. If you get married, there will be disasters and diseases, and one person may leave first and then leave the lonely other.

This is fortune telling. This kind of thing, I think, can't work if you believe it. Nothing is inevitable. It doesn't mean that men and women are destined to happen. Everything is random, believe it or not, hehe.

This is my reference opinion. Think for yourself. Good luck.
