Xingyunling

Xingyunling is the poly ship between Xingqiu, Chongyun and Xiangling. AKA: The Liyue Trio.

Canon
Xingqiu, Chongyun and Xiangling are childhood friends and have been having recurring cameos together in multiple events, especially during Lantern Rite. Though at first, the only evidence of their friendship was hidden behind their voicelines of each other, their first on-screen scene together happened during the Moonlight Merriment event (AKA the Moonchase Festival).

The three of them are all 4-star Liyue characters released during Genshin Impact’s first launch.

Voicelines
Xiangling only has a voiceline about Chongyun. She always sees him and Xingqiu together at Wanmin Restaurant to eat. She mentions how Chongyun doesn’t eat hot food while Xingqiu tries out every dish and that she wants to join in with his meal. She ends the voiceline saying the two of them are quite interesting.

On the other hand, Chongyun has voicelines for both Xiangling and Xingqiu. Chongyun says he doesn’t touch Xiangling’s food for personal reasons. Chongyun also talks about how he admires Xingqiu yet warns us of his mean side and asks us to come to him to form an alliance if we were ever to fall prey to Xingqiu's antics.

Lastly, Xingqiu has voicelines for both Xiangling and Chongyun. For Xiangling, Xingqiu explains how we should check the look on Xiangling’s face, especially if excited after collecting ingredients, as she tends to force others to taste-test her food. Xingqiu ends the voiceline mentioning how he lets Chongyun handle these situations if it were to happen. For Chongyun, Xingqiu states how Chongyun understands him quite well and is making good progress in martial arts. He ends the voiceline saying Chongyun needs more practice especially at eating spicy food. These two voicelines both end with a possibility that Xingqiu has Chongyun eat spicy dishes from Xiangling and that these voicelines are tied together.

Moonlight Merriment
The Moonlight Merriment event (AKA: The Moonchase Festival), was an event that catered towards Xiangling and Keqing as they made preparations for the festival. Xiangling was preparing for Masterful Chefs, a cooking competition, while Keqing was researching about the Stove God. During the first event quest, the two of them encountered Xingqiu and Chongyun at Qingce Village. Xiangling asked the two of them of their preferred food, to which Chongyun realizes she is partaking in the competition. He advised her to not cook anything strange but Xiangling assures him she is conducting research before coming up with her dish. After sharing their preferences, Xingqiu and Paimon praise Xiangling on her heart and pure intentions when cooking meals. This led to Xiangling being embarrassed.

At the end of the event, a cutscene showed of the Liyue friend group as children together which involved the trio along with Xinyan, Hu Tao and Qiqi.

Quotes
"When you first spot Xiangling out and about, the first thing you should do is check the look on her face. Especially when she's just coming back from collecting new ingredients — the more excited she looks, the more dangerous it is to approach. Because if she sees you, she'll force you to taste-test her latest concoction... I usually get Chongyun to handle these situations, hehe..."

- Xingqiu's Voiceline about Xiangling

"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

"Xiangling's cooking is universally praised, but I personally don't touch any of her spicy dishes. Why? Oh, you know — just, uh... personal preference, that's all. I mean, come on, Mushroom Slime Stew... Does that sound appetizing to you?"

- Chongyun's Voiceline about Xiangling

"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

"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

"Though Xiangling's market research blade stabs often into the dark, her heart never strays from the noble path."
