title: bing translator language code zh-CN or zh-CHS
body: <p>I have found that zh-CN and zh-CHS both of them can be used as language code, but why microsoft only tells me only zh-CHS can be used: <a href="http://msdn.microsoft.com/en-us/library/hh456380.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/hh456380.aspx</a>.</p>
  
  <p>Would it make any difference?</p>
