Stock Trading and Other Things

What are the Chinese websites for online trading?

I need to do online trading and purchase some beans and import it to other countries but I don't know specific addresses, I tried Google also but could not help.
Can anyone give me some Chinese websites address so that I can start my business?

Thanks.

2. the biggest website for oversea trading in China may be alibaba.com.
