There's an IPFS mirror of English Wikipedia[0], as well as several others[1], though not the Chinese one[2]. It's currently not a particularly up-to-date mirror, though (from late 2016).
There's a list of gateways[0][1] (hopefully github isn't blocked...) in case these two are also blocked. You could also try just using IPFS directly[2], rather than using an HTTP-to-IPFS gateway, though that's rather more involved and potentially might make you stand out more / seem more suspicious.
In brief, in case you hadn't read about it, the idea behind IPFS is that it's a decentralised, torrent-like content storage system, where content and nodes are "addressed" via their hash (e.g. QmXoyp... above), similarly to git. In order to allow people without the IPFS daemon to access the "IPFS web" there are gateways, like the ones mentioned above.
