A Three Way Combination necessitates the line that it transforms into, into becoming part of the Combination.
If the line it transforms into, can only interact with the the line it transforms from and still complete the Combination, how can it not also interact with other lines?
The rules I worked with suggest we need 3 active lines(day/month branch also work) and we have three way combination.
Do I understand correctly that you are looking at the resulting lines as what is joining the combination?
So for example we have line moving from something to Wei, Day Branch Hai and a line that is moving from something to Mao.
In that case the Wei resulting line and Day branch will pull the Mao resulting line to form the combination?
Or maybe Mao as central part is pulling the other lines?
Lets say 60 with 1,2 and last changing line moving to 20 yesterday

So here both Wei and Mao are in the resulting lines, so it will pull them to combination if I understand correctly.
But if its a original Mao line moving to Chen for example, there is no combination, as Mao is not the line after it changes, so other line and Day are just potential?Or they form arc maybe like in BaZi?
Lets say same example but without 6th line moving as well, then we have Mao moving, but it isn't resulting line, so it isn't part of the combination?

2. If we take the line that a line transforms into as being able to interact with other lines, Si Fire will Clash with Hai Water on the Self Line.
Yes, but then we get to the Clash when asking for potential boyfriend if Si does interact.
And as its someone she potentially doesn't know, so not a lot of relations already to show on Others, its easy to look at it as the clash showing they are moving toward each other...
I get the Officer line is on Self, so of course, it may not be beneficial, overall, I'm trying to figure out the rules for when Clash is something breaking apart and when its a meeting when there isn't an existing relationship and she ask for a timing of event.
So why Clash isn't beneficial in this case...
Do we just look for other Images, like in this case Officer on Self line, so it isn't in the other party, meaning there can be no relationship as more images show the clash as bad?
If its the Wei controlling Hai, and if we look at the clash we work with the rule that Si will interact, that is fine then the previous state of Wei controling her line shows the idea of countering I guess.
So the idea is that because Wei initially controls her line, also Officer is on her line, then we have enough Images to conclude next Officer/potential boyfriend that shows up won't work out, as she will be holding to Image on her own line and clashing the Other line with that doesn't seem open enough for it to work out?
Trying to clear out the rules for clash here, when its meeting something and when its braking apart.
Thank you. : )
