Unfortunately the upperpart pattern can't be seen in the photos - the description states scapulars same colour as mantle from which I take it that the whitish tertial tips which Yellow-browed Warbler shows at this time of year were not present (or not seen?). However, other features such as undertail pattern and the photo fit Yellow-browed Warbler.
Conversely, I would expect Emei Leaf Warbler to show a weaker supercilium (not reaching the bill) and a more obvious crown stripe. I also agree with John that Emei Leaf Warbler is in size and structure more like goodsoni.
So, whilst I would not like to say that this definately is a Yellow-browed Warbler, I don't think that Yellow-browed Warbler is convincingly ruled out and I don't think that this is Emei Leaf Warbler.
