Secondly, I admire Mr. Wu's academic attitude very much. I am very relieved to read Mr. Wu's manuscript, which is simply a kind of enjoyment, not as painful and horrible as reading other manuscripts. Teacher Wu is very concerned about the details in the manuscript. Many times, in order to draw a good picture, he has to communicate with me many times. By contrast, I am ashamed of my work. Finally, Mr. Wu is very meticulous. He will speak every question thoroughly, so that some people will say that he is verbose, but I don't think this verbosity is unnecessary at all. It's fantastic.
