Editor: We have to publish dozens of articles in each issue. Many authors have sent us a letter after receiving the sample for a long time, even after a long time, explaining the effect and response after the publication of the manuscript. Most of them said that what problems were solved and what kind of effects were produced. We listened to the news and accepted the letter. There are also some authors who give us some suggestions and opinions at the same time as we write a letter. This makes us not pay attention to it. What we think is that if there is any change, it will be crowned. In this issue, we have even sent a letter to a number of readers, all of which have been echoed after the publication of our article. We welcome more readers to contribute, let more people share your knowledge and experience: I also hope that more authors of this journal will tell us about the effect of the manuscript after the publication, so that we can read the consensus.
