Please help me find my song

Hello. Can you help me find my song ? I have been looking for it for a couple of years but with no result . Unfortunately I don't remember anything from its lyrics, but I remember its video pretty well. In this video two men were having something like a rap battle on a boxing ring and in the other scenes of the video an Asian man was running across the street and he was making some parkour tricks. This song I believe was popular between 2002 and 2005 year and I think its style was R&B . Thanks for the help .
