what's the meaning of 呢?
for example:
as answer to the question
"how are you"  你好吗?
i would say "very well, and you?" 很好，你呢?
but i don-t understand the meaning of the character
Is there someone who could help me? thx


well bro, i guess jada's explain is almost alright.  there is just one more thing i'd like to say. though those modal particles doesn't make much sense by themselves, they could change meanings when using with  pronouns and nouns. 

for instance, 你吗？= are you ( 这张照片里的人是你吗？is that you in this photo?)， 你呢？= how about you ( 我喜欢吃通心粉，你呢？= i love macaroni, how about you?)

see you

Well... 呢 is a modal particle, has no exact meaning, is just used to strengthen the expression. There are several modal particles we often use: 啊 吧 了 呢 的 吗 着 呗...
