J. K. Rowling wrote this book by a very traditional way that is fussy but patient. I had a conversation with Hao Xie and Chen Yu after this television program. Hao Xie do not satisfy himself very well recently,he thinks he worked two much for commercial films,besides he do not have enough ability to produce art films. I don't know why he has this kind of thoughts,because to be honest his commercial films are really okay.
