Shopping in China?? How to do it? Like I've heard, vendors will usually raise the prices by multiple amounts if you appear to be a foreigner. Also, I've never haggled in my life! Is there any specific phrases I need to know? Will a stranger on the street come to help me if they're English is good? Or am I just completely helpless? Haha. Any help is welcome. I don't want to get cheated, that's all.

When do you know when to use "Le" in a sentence? For example, why do you use, "le" in the sentence, "Jin tian ni zuo shi me le?" is I notice that many Chinese use le unknowingly in almost every sentence. Is it okay if I don't use it as often as they normally do?
