zh-cn is not a standard django language code. However, it's a language code that is supported by edx-platform (and tutor). So we must convert it to zh-hans, which is simplified Chinese. zh-hk and zh-tw are both converted to zh-hant, which is traditional Chinese. The list of languages supported by django is here: https://github.com/django/django/blob/master/django/conf/global_settings.py Close #7
