No, I don't see it this way. Normaly yes. But 2 points make a difference here. It's forbidden literature and the chinese view about books. If you talk to people who was JW when it was forbidden, they don't give the books away like in other countries, they not used in a typical d2d-way. Same in china. And the chinese people normally don't throw books away.
From what I know, mostly they smuggled books to china, no flyer or so.
In conclusion books come to china, given only to the jw and when given away, only for people who study. If they stop, they have to give it back. Also if they don't give it back, they sell it sometimes but don't throw it away.
