 I think I found number 6... well, nobody's mentioned it
 anyway.
 Go in the baggage claim area and stop just inside the door.
 Walk toward the pond room and let yourself hit the corner of
 the walls where the X is below:
          pond
    |---|-------
    |        x |
    |----      |
        |    o |
        |      |
 The trash can  o  should be behind you.  Hit the space bar.
 A door will open right above your head.  Jump on the trash
 can and then jump for the door before it closes.
 Inside you'll find Uzi clips, a gas bomb, and shotshells.
 It *will* take practice to hit it just right so you get far enough
 in to trigger the "Ancient Chinese Secret" sound.  The jump is
 about at the limit of what Lo Wang can do.
 Since this involves jumping... has anyone gotten through the
 end of level four -where you have to jump across the chasm twice-
 without using no-clip mode?  Doesn't seem like you can jump
 far enough to make it, yet even with no-clip, there aren't any
 secret tricks to use.  It's just too far. 
 Spent a couple of hours trying it without cheats and just gave up
 and no-clipped right on through.
 Anyone got an answer that doesn't need a cheat?  Joe?
