Xingyun

Xingyun is the slash ship between Xingqiu and Chongyun from the Genshin Impact fandom.

Canon
They are one, if not the only, ship who exhibits friendly, buddy-buddy interactions as stated by their stories/voicelines and Xiangling. They are also featured together in official arts. They speak highly of each other and in a fond manner as well, showcasing just how close of friends they are. Xingqiu is known to endlessly tease and pull pranks on Chongyun (making him eat spicy food, tricking him onto fake leads, etc) though tries his best to seem innocent, and sometimes even going as far to encourage Chongyun and buy him cold desserts. Despite all this, Chongyun still refers to Xingqiu as a fine and true friend.

In Chongyun's voiceover lines, he states that he admires Xingqiu for his devotion to chivalry and passion for reading, but has also seen the latter's mean side. He is a common victim of Xingqiu's pranks and antics. Chongyun's story also stated that Xingqiu gave him the idea that, instead of attempting to reduce the effectiveness of his congenital positivity, he should search for an evil spirit that is immune to it. Xingqiu often gives him fake intel of sightings of evil spirits, and they come home empty-handed. Chongyun has no idea and blames it on his bad luck. Surprisingly, Xingqiu will try to lift his spirits after his pranks, doing things like getting him cold food.

In Xingqiu's voiceover lines, he states that he and Chongyun understand each other very well, implying they have been friends for a while. He also states that whenever you see Xiangling out and about searching for ingredients, she'll try to get you to try her newest recipe. He says that he'll usually get Chongyun to try it out. Xingqiu's story also stated that Chongyun is the one who usually bears the brunt of his bizarre humor. Just like in Chongyun's story, it talks about how he often pranks the latter by giving him fake intel, setting up traps in areas Chongyun practices in, etc. Xiangling's voiceover lines even have her stating that she always sees Xingqiu and Chongyun eating together at Wanmin Restaurant.

In-game, many users enjoy their elemental chemistry; as Xingqiu is a Hydro user and Chongyun is a Cryo user, both use elements that work very well with each other and are able to apply the "Frozen" debuff on enemies when working together.

Quotes
"Chongyun has had the privilege of meeting a true friend in his long journey as an exorcist: Xingqiu..."

"If Xingqiu has time to spare when such an occasion arises, he will encourage Chongyun, treat him to some new cold dish that he has found and then set off to get Chongyun's swindled money back."

"While quiet and unassuming in front of strangers, he is gregarious and chatty in the company of close friends and family. Though more restrained than his elder brother, he even has a playful and mischievous side."

"A warm and reliable companion indeed! — So Chongyun thinks at such moments. Who could he possibly trust, if not his fine friend Xingqiu?"

- Chongyun's Story 4

"I do admire Xingqiu for his devotion to chivalry and his martial arts proficiency. However, I must warn you that he definitely has a mean side too. If you find that you fall foul of any of his antics, come to me and we'll form a "Victims of Xingqiu" alliance. There is strength in numbers."

- Chongyun's voiceline about Xingqiu

"The one who usually bears the brunt of his bizarre sense of humor is someone named Chongyun, an exorcist usually found on one of the forest trails around Liyue."

- Xingqiu's Story 4

"Ah, dear Chongyun. Though he understands me quite well, one has to exercise caution when teaming up with him to go on a quest. He is making good progress in the martial arts, but I would say he hasn't quite internalized the chivalric code yet... He needs more practice. Especially at eating spicy food."

- Xingqiu's voiceline about Chongyun

"...I usually get Chongyun to handle these situations, hehe..."

- Xingqiu referring to Xiangling's new dishes

"Chongyun? I always see him on his way to eat at Wanmin Restaurant with Xingqiu... Ah... or perhaps I should say I see him being dragged there by Xingqiu? Chongyun doesn't eat hot food. Every time the hot food arrives, Xingqiu politely apologizes and proceeds to try every dish. I just wanna dig in with him! The look on Chongyun's face is priceless. They're quite interesting, those two."

- Xiangling's voiceline about Chongyun

Fanon
Xingyun is one of the most popular ships in the fandom currently; they have over 1k posts on Instagram, searching XIngyun on Twitter will showcase many fanarts, and ao3 holds more than 265 works for them. The ship mainly sailed due to the popularity of the "Best Friends to Lovers" trope, and their dynamic. They are featured in each other's stories, and are introduced as close friends.

They are also exceedingly similar, both being strong, coming from influential families, seemingly not much at first sight, but having a more wild underside. Even outside character, Xiangling, says she sees them dining together and as the official artworks suggest, they are often in each other's company. Many people are fond of this ship as, unlike others, they have a canon foundation as being best friends. Additionally, due to neither of them having any confirmed love interests, or much interactions with the other characters in general, this ship is very popular nonetheless.

Their dynamic is a very enjoyable one to highlight in fanarts/fanfictions, as their roles can be switched in many plots and it would still make sense. They are both hardworking (with Xingqiu being more smart with his methods) and overall quiet near others, but expressive in the presence of each other. Basically, they both know, to an extent, the real nature of the other. They don't exactly fall into the molds of other popular ship dynamics either (the chaotic duo, huge flirt x oblivious/uninterested, rivals to lovers, sweet x scary), but are more so of a mixture, making them a fun couple to portray. Since the information on their relationship is limited, most of the ship and it's headcanons are fanon, whether that's a bad or good thing.
