The Chinese factories are very straightforward. Buy some modest quantity, somewhere around 10 units, and they'll put any markings on there you want, for free. And if those markings just happen to belong to somebody else, well, that's on the buyer who specified them, not on the manufacturer (or at least, that's how they figure it in the mysterious Orient). I first noticed this with Yanagisawa saxophones for $279 - on Amazon. Real Yanagisawas are $8000+ horns. The "Yanagisawa" markings were very slightly blurred in the photos, as if that somehow made it less of a legal liability. I later saw some high-end Yamahas and Selmers at similar prices but with the markings not blurred at all. Sometimes they'll use photos of the real thing - apparently in China that counts as "close enough".
In any case, fake fake fake.
The honest Chinese instruments are usually copies of established models, either fairly faithful copies or, well, not so faithful. But the won't have somebody else's name on them. But the comedy never stops, as they'll almost invariably say "handmade" and "professional" in the ad copy, which is, of course, a bit of a stretch.
