Consider seeing HuangShan (Yellow Mountain). As with most major mountains in China it's not going to be a completely wild experience (there are still cablecars, paved paths, and hotels on the top), but compared to other Chinese mountains I've seen it's much less developed and crowded, especially if you stay up there overnight. There are also some out-of-the way / longer paths where you'll likely be the only person there, especially in the off season (I was there in November - it was beautiful). Also, it is not considered a sacred mountain so there are no temples there, etc (and also I didn't see any souvenir vendors and such, the only commercial places were the few hotels and cablecars). As for wildlife, I've managed to see wild monkeys there! As well as smaller animals (I think there was something like a chipmunk or a squirrel, don't remember exactly). Oh, and don't confuse HuangShan with HuaShan : )

Maybe consider some place like Zhangjiajie Forest Park, but in the winter time- it should be less crowded.
