The last guy to arrive at the school is a guy named Longwang, who's been late for class all the time. He's a commissar in charge of studying, so he's got a lot to say. Longwang is 17 years old and has been tardy for the whole school year. The teachers have labeled him a "repetitive tardy violation" , which means he'll be punished for every late arrival for the rest of the year. He tells Longwang to tell us what he did on his summer vacation. He doesn't want to talk about the most important thing in his life, but he does want to tell Longwang about what's really important to him. He complains about how he has to use a cell phone to keep up with the weather, and how his dad won't allow him to go back to school until he gets his high school diploma.
