It's a Young and dangerous alike series, but with low budget
We have only two of these movie in DB:

Street kids: Final combat
Street kids: Early life(which is also made in 1999, and not in 2000. should be changed)


There are another 5 (at least) movies in the series

Street kids: Macau warrior
1999
Starring: Mark Cheng, Ken Lok, Suen Kwok Ming












Street kids: Underdog
1999
Starring: Mark Cheng, Chan Kwok Bong, Ken Lok











The following three with no known year (for me), but since Street kids: underdog is the last movie of the series, so also these movies were made before 2000. I prefer to give them all 1999 as an estimated year. I hope the chinese titles are right

Street kids: Las Vegas encounter
古惑仔之大戰拉斯維加斯
Starring: Chin Siu Ho, Ken Lok, Suen Kwok Ming


Street kids: Sino combat
古惑仔之龍在中國
Starring: Chin Siu Ho


Street kids: Rage to kill
古惑仔之衝出亞洲
Starring: Chin Siu Ho, Yeung Yuk Mui, Ken Lok

So glad you posted these!

These are the same good folks behind the Bond's Angels series. Stuff like this got Hong Kong cinema through some rough times, so it's good to see it getting some recognition, crappy as most of it is! And these date from that period where Chin Siu-ho was letting his hair do most of the acting (a la PURSUIT OF A KILLER) so there's bound to be some fun...

I've got about four of these so far, but have been looking for the others. Looks like you lucked out! So to speak...

EDIT: Looks like we can ad the ever-reliable Ben Ng to a few of these. He's on the covers for SINO COMBAT and LAS VEGAS ENCOUNTER for sure. I'd love to know if they actually shot that in Vegas, or just stuck a roulette table in a hotel room and called it a Casino like they did in the RAKE GAMBLER series.
