I come from China, and I can't speak Japanese. I know the first sentence, but I can't. Please mark it with Roman characters. Thank you.

This sentence is most like Japanese spoken by people who can't speak Japanese.

But this is too straightforward. .

So it's better to say it in English. . .

I am so handsome. I said I couldn't speak Japanese. Give me another Japanese sentence. . . . .
