Hi Wangjinting! Are you still looking for an answer to the question that you posted a month ago on Talk:Main Page? If so, I'd suggest checking out the new "How to ask for help" section on the Main Page - maybe IRC or Stack Overflow would be more helpful places to ask this question, since mostly people use this wiki for reference instead of discussion.
