While it's not a romance, Oldman has romance in it. Oldman's by far the best manhua I've read.
Ayeshah's Secret is good, but romance is only really in it towards the end, since it's not the main plot.
As for flat-out romances: Chao Hua Xi Shi is super adorable, Tianjiang Xianshu Nan isn't quite my jam but a lot of people like it, and I haven't read The Prince's Cactus is a million years but apparently I gave it a 7/10 on MAL when I was 20. And I'm not huge on it now, but I think I enjoyed Wedding when I first read it. But yeah, Chao Hua Xi Shi is a definite read if you're looking for a cute Chinese webtoon.
does anyone have actual good straight romance manhua (chinese comic)? so far i only like hidden love and eternal love. i rarely find good straight manhuas lol.
