Very few Chinese understand much about crypto and most don't even bother trying to work out how to access blocked websites (they just end up using Chinese websites that are more or less equivalent - so Chinese search with Baidu, post photos and information on Weibo and watch videos on Youku and Tudou).
Most Chinese (including the countryside workers) would have a mobile phone though and more and more would be smartphones so their might be some interest in using smartphone for payments but keeping their bitcoins securely stored would be a big problem.
That being said the government so far has not been anti-bitcoin (several reports on CCTV have been quite positive and CCTV *is* the government mouthpiece) also their banks let you buy gold and silver currently so who knows maybe Chinese banks will be the first in the world to let you set up a BTC account.
