I see. Yeah, the Chinese scanlation scene is very advanced (just like with everything else they do) and, from a personal taste standpoint, does generally better titles than the English counterpart. I still remember randomly strolling through some Chinese online reading sites and finding some eroge-based titles like Yumina (way before it had an English translation) that I never knew had manga adaptations.
I'd recommend the people over at Yande.re -- they do debinding and other such practices daily (just with magazines and artbooks, not manga). You can probably find some tutorials around the forums (not sure where if any at all). None of them are active here at our forum, however, so your best bet if you want someone easier to reach is its very owner: Checkmate.
