I never studied German. However, as what my cousin told me, German is not difficult to pronounce, but you should try to memorize the grammer. btw, the 颤舌发音, i dont' think it is difficult and most Chinese can pronounce it well, at least those who studied/study Russian.
ps[火]-星海, your words recalls me someone similar to you. it seems that we will have some fun again. kaka.
