It is just that none of that has anything to do with his techniques being 'discordant'. Most of it is just that his anam pool isn't stronger and he hasn't integrated much outside of his strong hits.
Switching his technique aspects doesn't even help with this.
What do you mean? Our core does
in fact give us discounts on techniques with at least one of those aspects, both in learning them and in using them.
Warrior doesn't have a problem with Zhi integrating Charm in Full Flight despite it not having any of the core aspects in it either so besides the element having a host of techniques that actually synergize with one another might also be a thing.
In the case of Charm, it is a martial technique, it's not anam-based at all. Like, sure, it's not one that any Seated is ever going to learn because of the attribute requirement (Dexterity 4, whereas a Seated will likely peak at 2 if lucky), but Zhi is doing this purely body with his body, not involving any of his spirit.
I agree with the rest of your point, though - Zhi's techniques are pretty... eclectic. Haphazard. Disorganized. Random.
I don't think it's currently a huge deal, but it's
definitely true that Zhi picked up these techniques basically as he went along just because they showed up. The Hummingbird's Dance was taught by Daiyu. Warhound's Cry was a gift from Nokai. The Stallion's Enclosed Garden was from our family. Worldstream was a gift from the Sen. The Twilight Horizon was from Ma Rongjie's inheritance. Blooming Spear of the Auroch and Shatter the Mirror were self-made, but based in part off of inspiration from the enemies we defeated.
Just about the closest Zhi got to being able to
plan out his techniques was choosing Shadow of the Prince and An Elegant Plume from Siani. Searing Chariot was... well, we should have tried to narrow it down further with "try to find a Smoke or Steel tech".
