Disclaimer: I haven't bought my first Chinese frame yet but aiming to do so by the end of the year. From what I've gathered, I'll try and organize from least to most reputable. I'll delete the ones I don't know.

Airwolf (from what I've heard, garbage)
TanTan (fine frames, bad customer service)
Toseek (didn't know they make frames, but their carbon Ali stuff is generally well-reviewed)
Velo Build (fine, quality varies. Apparently getting better)
Light carbon
Longteng (I think the sweet spot between quality and price. I'm shooting to get the 301-D)
Dengfu
Hongfu
Yoleo (expensive)
Elves
BXT (boring frames)
Carbonda
Yishunbike
Og Evkin
Ican
Seka (almost completely legit now)
Polygon (graduated to a legit western company at this point)
