I am looking for a table of the regular phonetic correspondances between the different chinese varieties (Yue, Wu, Gan, Min, Mandarin...). For instance I noted a g (Yue)/j(mandarin) correspondance (e.g. ga/jia). There must be more, already documented.
Any advice where I can find descriptions of these correspondances on the Web? I can only find very high level considerations so far.
Thanks beforehand!
