I'm after a particular song which is not on the Soundtrack

It's the song that plays about 3:06 - 4:25 of the movie. It's when Junbao and Tianbao watch the other kids practice Kung-Fu and then they get hit on the head and pushed to the ground by the bigger older kid, then they go to the master and shield his head from the sun...

There is a song with the same tune as this song on the soundtrack which is track 25 which I have, but it's a different version to the one when they are kids. I'm after the version of it when they are kids...

If you can help me find where to get this track, I will be greatly happy...

Cheers in advanced...
