I use unotelly for this. Can access youku, tudou, eye. See their supported channels list too see what is supported
Although their vpn service is crap, I only have good things to say about their dns service so far. Eg, they only officially supported xiami on pc/mac. I submitted a ticket on 26 asking if they could support out on android as well. And they added support for this and replied to my ticket on 30th.
Apart from unotelly, astrill is the only other service which I know of that can be used to access china content. Someone reviewed it a few pages back.
On my opinion astrill, as a full vpn service, is guaranteed to work with any site. But service quality may suffer with popularity as china bandwidth is very expensive. On the other hand unotelly's dns service must add support for each specific site but service quality should theoretically not worsen with popularity.
