ONE of Jay Chou’s most well-known songs is Nunchucks, or Shuangjiegun in Chinese. The rapid pace and rap lyrics of the song, especially the skillful whirling-nunchuck (耍双截棍) performances of Chou, never fail to heat up his concerts. However, the singer’s indispensable prop (道具), the nunchucks, actually got him into trouble when he went to Australia on April 11 during his world tour.
