So please come (if you speak enough Cantonese to function in it, ideally also recognise some Chinese characters, AND) if you're interested in learning Classical Chinese. I have some little anecdote(s) that you'll be reading. And, as we gradually encounter grammar and vocabulary that differ from Cantonese, I'll explain those things. As a side-benefit, learning Classical vocab. that differs from Cantonese will increase your Cantonese vocabulary, because these Classical words do occur within compounds in Cantonese, and we'll pay attention to this.
-- (Classical Chinese, in case you might not be sure what it is, was the literary language = how speakers of all Chinese languages --unless they were purposely using an informal style-- wrote things up through the 1920s, in which decade, then, the "May-Fourth Movement" occurred, which led to the teaching of Written Mandarin in Chinese schools.)
