Yu Hua was a famous author whose works had always been appreciated by readers. There were several possible explanations for why he stopped writing about blood and violence. One possible explanation was that Yu Hua believed that the violent and bloody content might make the work depressed and heavy, unable to bring true happiness and satisfaction. He believed that good literature should be able to convey positive information and emotions rather than emphasizing negative and negative content. Another possible explanation is that Yu Hua has reduced the frequency of his writing as he grew older, perhaps thinking that he has found a more suitable way to write. He might also think that writing should focus more on the inner world and life experiences of individuals rather than emphasizing violence and gore. There may be many reasons why Yu Hua stopped writing about blood and violence, but I think the most important one is that he found a more suitable way of writing and believed that violence and bloody content could not really convey positive information and emotions.
