武汉话 is a 普通话 dialect, but at its most extreme is incomprehensible (right down to having a fifth tone!) to 普通话 speakers. It is, naturally, also one of those dialects for whom "四十四是四十四十四是十四" comes out as "sisi si si sisi si sisi si sisi".

I knew quite a few people who spent time in Foshan. They seemed to like it as a laid-back place like Shangrao in Jiangxi province for those I knew from there.
