How to use text-to-speech in mandarin?

hi, 

I'm new to CapCut, still learning how to use this great app. One feature that I love is text-to-speech, however, I couldn't make it work for chinese text removed link May I know how do I enable or add the chinese text-to-speech function? Is this a CapCut Pro feature? 

Also, would like to know if we mix 2 languages in text, such as "我和朋友去shopping mall”, would the text-to-speech able to pick it up? 

thanks
