In this short scene, we learn that the protagonist, Lin Hai, is a poor rural boy from the countryside who has been trained by an average music teacher. Lin Hai has no idea how to sing or how to act, and he's not very good at it either. He's a total loser, and Lin Hai is the one who won the singing competition last year. He wants to humiliate Lin Hai by challenging him to a singing contest. He offers Lin Hai a prize of 100,000 yuan if Lin Hai wins the contest. If Lin Hai loses, he'll have to pay the prize money back to the winner. But if he wins, the three of them will have to "bark three times like dogs" in public to prove that they've learned their lesson. This is a big deal, because Lin Hai doesn't have the money to pay back the prize to the loser. But Lin Hai isn't going to back down, so he promises to show the other students where they belong.
