May i tell anyone of you a joke here?
I started practicing the rr sound when I started learning Spanish,
at last, my tongue moves just like a piece of paper when I try to pronounce rr.
At first, I thought I was right. I could make my tongue moved in this way only,
but not reading any words. So finally, I knew that I had practiced one of the skills in playing Chinese flute successfully but not the rr sound...
Thx a lot for all who have helped me!! I will practice it and must pronounce it correctly!!YA!!!
