Is the humorous joke a male monkey or a female monkey?

There is a daughter-in-law who is not sensible, so she is smart.

One day, her husband came back from visiting relatives and said angrily, "Look at his daughter-in-law, and then look at you ..." The daughter-in-law was unconvinced and said, "What's wrong with me?" The husband said, "Everyone knows that books are polite.

As soon as I entered the door, people asked me what your name was. I said my surname was Zhang, and people asked me if I was a longbow or an early chapter ... "

A few days later, there were guests at home, and the daughter-in-law learned to be gentle: "What's your name?"

The guest replied, "Last name is Hou."

The daughter-in-law asked again, "Is it a male monkey or a female monkey?"

The guests were dumbfounding and speechless.
