:I'm sure you are not a student of cinema because what you said makes no sense.  Do you know who was making significant cinema under the KMT in China?  Leftists and communists (true ones, not the Communist Party aka cult of Mao).  Do not go around bullshitting or assuming things about history that aren't true, i.e. "oh, but didn't KMT go to Taiwan and wasn't KMT in China before?".  BUT THEY WEREN'T MAKING THE MOVIES!!!! 

 :Huge influences on Chinese cinema that have nothing to do with HK or Taiwan: 1) Shanghainese intellectual leftist early cinema 2) Communist propagandistic, didactic films 3) Great Leap Forward / Cultural Revolution / censorship 4) 5th generation reform of films (where the subject is always CHINA!!! (yes in big letters, the big, imaginary, essentialist idea of China, i.e. Chen Kaige's Yellow Earth). 

 :Responding to your nonsensical position that they are all Chinese-language cinema.  Do you see a page called English language cinema?  Do you know that American pop culture dominates especially in English speaking countries, aka UK and Canada and that there is much more exchange between the three than between Taiwan/China/HK?  There is not much travel between Mainlanders, Taiwan, and HK, mostly because Mainlanders are poor as fuck and because it's a security risk to Taiwan, and because HK has a separate political system (though the reverse of Taiwanese and HK going to Mainland is big).  Yet, there's no English language cinema.  You are making the case for an additional page called Chinese langauge cinema, or actually more properly, something like International Chinese Cinema that is a very recent, not historical phenomena.  You're out of bounds Jiang, learn more about the topic before you make ridiculous assertions like that.  I bet you've never seen a Chinese film prior to the 80s or 70s, if even that.  Being that your knowledge base is so weak, I would have to say that what you're basing your opinion on is your political views as reflected in your foolish comment about "glorious Chinese culture".
