"The fairy sent the Americans home. The Frenchman went on to say, "My first wish is to give me many beautiful women. "The gods gave him many beautiful women." My second wish is to have many beautiful women. "The fairy gave him many beautiful women." What about your third wish? ""take me home! "The fairy sent the French back home.

" Americans and French, afraid of being called back by China again, shouted: "China people say their wishes first." The fairy looked at the Chinese, and the China people said, "My first wish is to give me a bottle of Erguotou." The fairy satisfied him. Q: "What about your second wish?" China said, "I want nothing more. Go ahead. " The fairy disappeared. The Americans and the French looked at each other.

The three men walked on, and then they found another bottle. When they opened it, another fairy appeared. The fairy said, "I am the younger brother of two immortals you met in front of me."
