I am not saying it is the "complete" list of Chinese achievments in CS. I just copied it from somewhere on Web. It is defintely an incomplete list of hardware advances in China. I am not even trying to give you a whole picture of Chinese computer technology, as it is out of my knowledge base. You heard nothing from China does not mean that nothing happened in China. Even I tell you that something did happen in China, you would say it was meaningless because it has no impact on computer technology in US.
