Fill in the blanks according to the passage. He Kun pointed to a dog and asked, "Is it a wolf or a dog?

Appointed assistant minister and appointed Kun as minister. He Kun pointed to a dog and asked if it was a wolf or a dog. Ji Xiaolan is alert and sober, and he is insulting himself. He replied: the tail is a wolf and the vertical is a dog. In the joke, "Wolf" is homophonic with "Assistant Minister", and "Vertical" is homophonic with "Shangshu". Literally, it means one thing, but in essence it means another.
