Darn that's funny! I still don't know chinese and never will. My buddy and I were going to do a video on building a bike I decided I didn't want to cause my language would be mostly 4 letter words I get a little nasty when working on things and have been known to talk to them. I can see you holding a perfectly flat sprocket and wondering which side is dished. LOL ! Maybe a good comedie "build a bike with instruction no one can understand".
Don't take this personal its just struck me as being funny.
