Question: In the lunchroom cafeteria scene after Cheng sadistically and purposefully slams Dre's lunch tray all over him and knocking it over, Cheng says something to the teacher in Mandarin that is omitted by the English subtitles before Dre yells "Whatever he's saying, he is lying." What is Cheng saying?
Question: Why are Cheng, Liang, Zhuang and all the other boys so mean to Dre and why do they hate Dre so much even when Dre minds his own business? When Dre leaves them alone, why don't they leave Dre alone? They seem to be attacking Dre for no apparent reason like they're psychopaths. Are they purely malicious and evil at heart?
