@OryB23904 right,Especially in the case of women,
Chinese women seem to have finer, more delicate bone structures. When I saw Jang Won-young, I also thought she had the kind of bone structure typical of Chinese women; Korean bone structure tends to be a bit larger and sturdier.
Here’s a Uyghur-Chinese woman who she is from XinJiang and now living in Guangzhou. Let her speak to you in Cantonese ( oh no😱 that’s cultural genocide according to the West).
