White boy tortures and interrogates Chinese Civilian in PERFECT Chinese, they are rendered speechless

A little context, this guy is a youtuber and all his videos are titled like this

aside from his mandarin, basically every one of his videos where he 'speaks fluently' in one of a hundred other languages involves him basically stammering repeatedly while trying to get out a simple phrase, as though the elongated time it takes him to say
'I-I-I-I've b-b-b-been l-l-learn-ning f-f-f-f-for t-t-two w-w-eeks' counts as a lengthy, fluent phrase

I hate languages.
