Ooooooh!
When watching Feixiao PV, I was thinking that the PV is evidence Jing Yuan is Cantonese, because of Feixiao's comment on the food being under-salted. Canton cuisine is know for being of a lighter palate, and if Feixiao's cultural inspiration is from a more modernized place, like Shanghai, then it makes sense why she'd find Luofu food to be "too light". (Shanghainese cuisine is known for being salty.)
Then, as I looked up location names for Luofu ship (for fic reasons), I realized it's named after Luofushan tourist region. Quote:
方圆260平方公里,共有大小山峰432座、飞瀑名泉980处、洞天奇景18处、石室幽岩72个,山势雄伟壮丽,自然风光旖旎。罗浮山,素有岭南第一山之称,秦汉以来号称仙山,史学家司马迁把罗浮山比作“粤岳”,是中国十大名山之一。
I feel like I should've figured this out sooner. But also, apparently 朱明洞天 is one of it's 18 major sites, further evidence that the tourist region inspired the game location. (BTW 洞天 is translated as "delves" in English version.) Am surprised English wiki fails to mention this.
Also found 卜易局 and am having waaaaay too much fun feeding names into it.
