I can't locate PO files to translate. After I login the http://publictest5.fedora.redhat.com/submit/module/, I choose a module to review the detail. When I click the zh-CN (simplified chinese) entry and the download icon, no of them can link to the PO files need to be translated instead of Simplified Chinese community .
This bug has also been reported on bug report #381521. To receive the PO files for translation, one should use the statistics interface, over at http://translate.fedoraproject.org/ and use the green "download" arrows next to each language/module. The /submit interface is designed (for now) to only commit files. *** This bug has been marked as a duplicate of 381521 ***
