I think the problem is that y'all are stereotyping Ionia and including every little thing of eastern origin, even things that have nothing to do with Ionia such as the Chinese New Year. That has nothing to do with Ionia and everything to do with China. Fiora has floating sword chinese movie skin. Does that mean she's Ionian too? What about Nasus's and Warwicks's yinyang doggo skins. It's too much of a stretch so say "Talon has an Ionian skin, that means he's Ionian!"
The entire point of skins is to reimagine champion designs, after all. Poppy has a Noxus skin but she's Demacian. As a amtter of fact, so does Lux and Fiora. Shyvana has a Freljord skin. Amumu has a Canada skin. Just take skins at face value and leave it at that until the lore comes :D
