I think I found this on Taobao. It looks similar, and there’s a color option called Hydaoqing.
It’s being sold under the name “Chassis”. They also describe this as a European/American-style yo-yo.
(Update) Unfortunately, this may be a imitation of the unreleased A-RT Yo-Yo. Or it could be an imitation of a diptych with a few minor modifications.
The Taobao seller shares a similar name with “Fingerspin Prince,” who produces the A-rt knockoffs mentioned at the beginning of the linked post.post above, is selling this item. I’m so sorry to have to break the bad news and spoil your fun.
