Tell a joke: How did Mulan get caught pretending to be a man?

Mulan disguised herself as a man and joined the army for her father. She buys equipment first, horses in the east, saddles in the west, reins in the south and whips in the north.

Arriving at the barracks, the general asked, Are you a woman?

Mulan was surprised. How did you know?

The general laughed: which man can go shopping so much?
