Not too sure what your definition of "beautiful" is but here is a chinese one I recommend :

Not only is the art beautiful, but so is the storyline!! Once again, not too sure what you consider beautiful, but this is what I see it as :)

the most gorgeous art in my opinion is in remarried empress. furuya nagisa's mangas also have nice art
also good mentions: at the end of the road, heaven & hell roman company, general please stay, the villainess lives twice, does love need a translation app, the tyrant's first love, ebony, death is the only ending for the villainess, a stepmother's märchen, glen, beware of the villainess, i'm stanning the prince, spy x family, seduce the villain's father, nan hao & shang fen

I recommend "the horizon" its interesting but also depressing.. if you read it be prepared for tears all I gotta say and the art style and just the scenes are so beautiful to me

I just finished innocent and boy that was beautiful

woahh thanks for all the recommendations guys (づ￣ ³￣)づ
