Does personality insight API support simplified Chinese?

Hi, I'm trying use personality insight API to get personality and value scores from social media posts in simplified Chinese. I find there do support Chinese in the API document, but I get the error when I doing so. Error info is {"code":400,"sub_code":"C00001","error":"The language you requested, zh-cn, is not supported. Languages supported: en,es,ja,ar,ko."}. Can anyone figure this out? If so, what is the code? THX!
