The original text is as follows:

One day, a scholar went to a friend's house on business. An enter a door, he fists a hug, politely read a crossword poem:

A cow in front of the temple, (special)

Two men were carrying a dumb log. (coming)

Speak before entering the door, (ask)

The woman in the boudoir covers her head tightly. (Ann)

After a little thinking, my friend understood what the scholar meant. He also answered politely with a crossword puzzle:

It's true that the green hills are not green, (please)

Two people are talking on the ground. (Sit down)

Three people ride a horn cow, (Feng)

There is a man standing in the vegetation. (tea)

Please sit down and serve tea.

Hearing this, the scholar was absolutely right, and both sides couldn't help laughing.
