I saw your post about Xiang Fei and, as a woman and a Chinese person, found it interesting. I did a little digging, and found a higher resolution version:

(The colours may appear a little faded, but her face is similar enough to my own skin tone that I don’t think it’s been deliberately altered.)

What is interesting is that another version of this painting exists. Because I don’t know the name of this other version, it’s been hard to find info on it, but all evidence seems to suggest that it’s a reproduction:

What is interesting to me is that not only is her face distinctly more European in this later version, she also appears less comfortable in her armour. Unfortunately, I have no idea when this reproduction was made, where it was found, or if the painter is from the Occident or Orient. Given the high level of accuracy in the rest of the reproduction, the altered face is probably not an accident.
