This isn't Chinese. It's a Bali-themed girl, and that's Barong's mask. Another indicator is the batik-patterned stockings.
The Japanese school uniform is because Zounose made the art to promote a Japanese school culture festival.

Stockings only cover up to the thigh, so I fixed the reference for you.

I see that I still have a hard time differentiating between the two.
Thanks

Its not all your fault. Most of the internet has the same problem.

Well, you've corrected me on this before, so I should've learned at least.
Maybe because I rarely remember the word "pantyhose", instead just either stockings or thighhigh

Pantyhose are commonly called "stockings" in America for whatever reason. Probably because "pantyhose" sounds less refined, having the frilly name of underwear in it.
