A scholar was preparing to take the civil examinations. His
wife was very puzzled by his constant worrying.

"Look at you, you worthless wretch," she said. "Your probably think
that it's more difficult for a man to write an essay than for a woman to give
birth to a child."
"How's that?", she asked.
"You women can bear children easily because you carry
the child in your stomach", the scholar said. "But I have nothing in
my head, so how do you expect me to think of something to write?"
