There are different prouncation between xing and hang. You use tell them from the contexts. For English, I like you. I am like you.(how do you tell when 'like' is used as foundness or similar to...）

According to my experience, "Xing" is for verb, even in "xing li"(luggage, it is a noun.) , but "xing" is the verb, "li" is the noun in this word. "Hang" is for noun. Hope it will help you more or less.
