A poor man took the position of a rich man. Who is the full text satirizing?

It satirizes those who have to face up to suffering.

The book Jie Gu Bian compiled by Lotte Laughter in Ming Dynasty tells a joke that a poor man went to the table of a rich man, but served Ge without fur in winter, for fear of jokes. He deliberately waved a fan and said to all the guests, "Some people are afraid of heat, although it is good to be cool in winter." When the wine dispersed, the shopkeeper thought it was fake and pretended to please. He just put a cool pillow on the pavilion of Lake Suchi-it was too cold at midnight, so he left with pyrene in his urine and fell into the swimming pool: the owner looked around. He was surprised to ask why, and the poor relatives said, "I am afraid of the heat because I am isolated from the world." Although I stay in the pavilion in winter, I have to take a bath. " As the old saying goes, "Laugh at poverty and don't laugh at prostitution."
