This is a weird music video for the song called, "Jumping Off A Roof." It's not a song about suicide, it's a song title dedicated to the type of stuff Jackie Chan is good at surviving for entertainment.
The song "Jumping Off A Roof" comes from the album called, "Jackie Lee Vs Bruce Chan Hip Hop Battle." The album contains songs titled in a similar way. Not all the songs are as scary as this one. The album is more about playing around with traditional Chinese instruments in the form of splurge concept albums and creating music for games and film/video.

Thanks for watching and look forward to another new video featuring a song from the same album, coming soon!
