In answer
- they come unassembled, like a normal Mystery Figure.
- They were 30 RMB, which is (very roughly) £3, and I think the normal price for a Mystery Figure - I bought one recently in a bookshop and I'm sure that's what I paid
- I only bought the Flapper Girl and the Egyptian Woman (I assume that's what she is) which have non-standard bodies, so I didn't see if the frames were grey, but everything looked 'normal' to my eyes.
I've posted pictures of the rest of the box

There's also a number on the top, I guess indicating you can 'collect' all of them.
Very intriguing! I think this is a case of unregulated – or, perhaps more likely: licensed repackaging. There must be tons of excess Figures in the factory at Malta. Perhaps Geobra made a deal with some Chinese entrepreneur in order to offload them.
This is what I would lean towards. The shop did sell regular Playmobil too, and the fact that it's in a shop and explicitly labelled as 'Playmobil' rather than a different brand name (the Lego piece-for-piece rip offs never actually said 'Lego' on the box).

It would surprise me that Playmobil would make something explicitly aimed at the Chinese market when they aren't really focussed on it (it seems to have disappeared from 'Toys R Us' here, and there's certainly been no effort to make sets aimed at the Chinese market like Lego has with the New Year sets they make)
