`  == Sentence about mutual intelligibility of written Wu ==  There is a great but not complete degree of mutual intelligibility between written Wu and Mandarin within the People's Republic of China as both are written in the current Vernacular Chinese, which uses Simplified Chinese characters as well as grammar and vocabulary centred on Standard Mandarin with a few allowances for ``regional variation``.  ^That sentence doesn't really make sense. Written Wu is as different from Vernacular Chinese as Wu is from Mandarin. If Written Wu were written in Vernacular Chinese, then it wouldn't quite be Written Wu, would it now?  I think it ought to be removed.`
