hehehe...
Funny you should mention that...
Where I go to school, one of the grad students on campus is from southern China, and after constantly asking him for the past semester, he finally started teaching me this past week. I can explain the grammar he teaches me to you, and even do so in pinyin as well as hanzi if you want, but I'm by no means qualified to explain pronunciations...I CAN, however, refer you to a good online dictionary, I'll be back in a few minutes with the link...
