I looked at his recent posts and almost all of them are in chinese. I certainly can't judge the quality. It's cool to know that you speak Chinese tho, hillarious. For some reason I thought you had told me you were Candian (not that there aren't candians who speak chinese, but that's certainly not the stereotype).
I see it may be hard for you to scroll down, like just a little but here im going to quote his last posts so you can judge:
Bitcoin and qora
All of them have poor quality + the spaces i was talking about earlier, you can just see it when quoting
