There are three riddles at the bottom.

Once upon a time, there was a fortune teller who was very effective.

One day, three scholars who came to Beijing to take the exam came here to ask for visas.

-

[answer]

Mr. Wang sticks up a finger, which can indicate that no one hits, or one hits, or one misses, or none hits.
