Thank you for your support and email about our Losing the Dark video.
We are working on creating spoken translations in many languages. We do have people working on the translation for both Mandarin and Cantonese. Is Mandarin the language that would work best for you or should something different be produced?
I do not yet know when we will have this translation completed and recorded, but can certainly let you know.
Let me know if you are just looking to use the YouTube version, but with subtitles, as I can help you with that.
