you'd better start learning Pin Yin first, that's the fundamental part. Later, you can pick up some easy vocabularies, some greetings, for example. Learn to pronunce the word slowly. That's the first thing first. I suggest that u should look for a teacher in ur hometown or city, and he/she will lead u step by step. coz I don't think anyone can master a new language by learning by himself / herself.
