Chen-Chou destruction = Earth produce Metal produce Water produce Wood. If wood is being produced isn't it one of her useful elements? being a strong DM?
I wonder about this.
Can we use Hidden Stems like that in combinations as well(follow produce cycle).
For example Wu - Wei.
Fire in Wu, Wood produces the Fire, Fire produces the Earth. Yet 2 fire stems. So we have a lot of fire and end of the produce cycle in Earth.
So combination creates fire.
Looking at it it seems all except Mao-Xu and Zi-Chou fit into this.
But we can say that Yi wood is diplomatic, so when all is against it is its best time to work. No idea for Zi-Chou and why that would create Earth...
Its very interesting, may explain much of the interactions and dynamic and also can point out to the exceptions to check why. : )
What do you think, could it work for the other stuff(combinations etc)?
