♡ First off, Jiang Cheng and Mo Xi are essentially the same person:

Noble, first born sons.

Same hair

Similar traumatising elements within their families. E.g. dead parents, elements of parental infidelity, periods of being very sad within their childhoods.

♡ Secondly, both get their entire worldview completely blown up, trashed and shit on by the narrative.

Jiang Cheng's pride over his achievements being damaged by the golden core reveal.

I'll only describe Mo Xi's vaguely because I'm trying to convince people to read Yuwu and there's heavy, heavy spoilers involved. BUT he basically risks his entire life to find out the truth about something and is under an Oath that will turn him to ashes and tear him out of the circle of reincarnation if he breaks it. When he does discover the truth it devolves into some of the hardest-core self-loathing I've experienced in a danmei I am certain Jiang Cheng fans will eat up.

♡ Thirdly, I originally bought Yuwu myself because Ximang was suggested to be Wangxian coded. They're not. In writing this post I have realised Ximang is actually a pimped up version of Chengxian. If you ship Chengxian, Ximang is the payoff you didn't know you needed or wanted. Allow me to explain

Ximang are plagued by thoughts that neither is good enough for the other, but Mo Xi is infatuated with the idea of building a home for Gu Mang. He wants to be his family with all his being.

Ximang will happily risk their lives for the other.

Ximang have all of the feelings but none of the communication skills.

If as a Chengxian shipper you are into the idea of Jiang Cheng being jealous of Lan Wangji, but Wei Wuxian being all in about Jiang Cheng, Ximang will absolutely scratch that very specific itch.
