What stories are used to connect several unrelated things?

I heard a story: my friend gave me a 70-year-old daughter's red, one of which was full of wine, and the rest was not willing to drink, and it was placed in the corner of the dining table. I showed off in my circle of friends and received a call from another friend in a few minutes. "Throw away that can of wine!" He shouted on the other end of the phone, "don't you know the story of daughter red?" Wudi has an ancient custom. When her daughter is born, she will bury a bottle of wine in the ground and dig it out when her daughter gets married. This is called daughter red! " "I know! So what? " I don't understand. "You think about it! What does 70-year-old aging mean! On behalf of her daughter, she never got married, or died before she was an adult! Great murderer! "
