Fendi was marketed as Chinese-Ukrainian mix. Which I've said a few times I don't believe.
Based on the poor English reported here, and the weird accent in Mandarin reported in the other review (as well as the physical description), this does sound a lot like Fendi. Who claimed she grew up in Beijing but did not have a Beijing accent.
I think she's Uighur. Uighurs can look European. Really more Turkish. And are taught Mandarin, but often don't speak it like native Han Chinese. My theory being her marketing team figured nobody knows what the fuck Uighur is and somebody's autocorrect suggested Ukrainian when they mistyped Uighur and they just went with it.
And once again, Uighur is WAAAAY more interesting to me than "Ukrainian Chinese"
