You mean you can't order a book online, pay for it online and have it mailed/shipped to you? That does make things more difficult. Skene's has been out of print for many decades, though as I mentioned, a recent reprint is on going. Used versions of this book can be found ($10 - 30 USD), though I'm not sure about the availability in your country or even if you're allowed to access sites where it might be available. As to the political and social "acceptabilities" you're having issue with, well this isn't the place for this discussion, but it is a well documented set of issues, though your access to this information may be intentionally limited by MPS (and other agencies).
I admit I'm certainly tainted in this regard, having had copyright protected designs, stolen and appear on a Chinese web site. The legal authorities in China were just about as useless a bunch, as I've ever known and our state department was helpless without Chinese cooperation. I'm not the only one to have had this happen and it's a common occurrence apparently, with continuous thefts on a daily basis and no recourse from Chinese officials.
it maybe a jest from my view, China don't like north Korea,although i don't know this country quite well,they won't kill me for what i said ,they will punish me if i break the law, i am not afraid of being monitored.thanks for your cares,that's ok. you mean you will send your copy of this book from cuba to china? it is too long and cost too much ,i have got one,thank you so much,you could send me email if you contact me,i don't know how to send by private message,anyway,thanks
