"Professor" Jiang (he's not an actual professor) has fed connections if not a fed himself. There's a Twitter thread about Jiang's background: https://nitter.net/zhen_ming_/status/2035083436860612639

He immigrated to Canada when he was 6 and he only learned how to speak Mandarin at college. He spoke Taishanese at home, meaning he most likely didn't know how to read Chinese characters until college either. Basically, he's a lot more removed from mainstream Chinese society than what he lets on. I don't think he even lives in China. People are just listening to an anticommunist Chinese Canadian with a vague foreign accent and thinks that he must represent Chinese Mainlanders somehow.

Oh and he also thinks that "Israel's success is due to it becoming a world laboratory, creating goods and technologies exported to the rest of the world."

Are you sure? Even if he spoke monolingual Hoisanese, wouldn't most of the text been in Chinese regardless? Most sinitic languages use the same basic script plus or minus some words for vocabulary differences because it's a logographic script.
