Yes, I live in Hong Kong now and I know the Chinese languages have ridiculously simple formal grammar (that doesn't mean their brain doesn't have to do complex inference - is it better not to say what you meant or simpler to just write it ?).

The ridiculous writing system is indeed my problem with it - and the ridiculous variations in tones too but they swear it's easy if you're born in it... which is ofc the problem: a lingua franca works if adult merchants can learn it.
