Xiao's joke

One day, a farmer named Xiang and a punk named Liu fought for a piece of cake. The farmer named Xiang was so powerful that he couldn't even beat the punk named Liu, so he called for help: a Zhang, a Han and a big brother of our Xiao family. Finally, several people joined forces and killed the farmer named Xiang, so Liu became the emperor. That's the story. Believe it or not, I do.
