Apparently this is an illustration of a Tripwire Lian Nu for use in an ambush.



What I do not get is how it really works. It seems that the wires are not in shooting range, and in fact, far away from it?

Is that because it has a fixed time delay? I mean, has the creator taken into account that arrows take time traveling in the air, and that by the time the arrows connect with enemy soldiers armor/flesh, the soldiers will be far away from the place they were when they activated the wire, due to the "time delay"?

I have no logic explanation I think, but it seems like if someone activate the tripwire, there is only a medium to low certainity that the Lian Nu will hit the target? Or am I wrong?

How does the tripwire Lian Nu work in detail?

PS: Is the tripwire supposed to be that short, or is that because this is only an illustration of how the principle works?

Perhaps liang jieming know this? (I think I got that illustration from her homepage or something)

hehe. I hope you aren't dissapointed it isn't that pretty lady on his avatar.

Sez who!? I really look like that in a skimpy bikini!

Ok, back to the scholarly discussion. That's probably just an artistic representation of tripwires, meant to give field engineers/soldiers a general idea of how they should work. The manuals are full of such general illustrations, which rightly assume that the engineers/soldiers can figure out not to apply them literally but with common sense.
