It's a real joke to remind the rich man to ask small long-term workers to make wine without giving money, and also to say that it is the real skill to earn wine back without giving money.

The rich man asked the small long-term workers not to pay for the wine, and said that it is the real skill to call back the wine without paying. The laborer went out with a hip flask. After a while, he returned to the rich man's house and handed the hip flask to the rich man. The rich man was very angry when he saw that there was nothing in it. As a result, the small long-term worker said: "Anyone who can drink can taste it, and no wine is the real skill." The rich man is in distress situation.
