When I woke up today, I received my shelf notice, and I was shocked that the editor didn't tell me in advance, so I was almost at a loss, I didn't tell everyone, and I didn't keep the manuscript, and today is still a full class, and there are still many things to do.

First of all, I want to apologize to the readers who are chasing the article, because I am signing up to write a book for the first time, and I am not very clear about the process, and it is almost so confused to put it on the shelves, maybe some of you are chasing my book because it is free. I'm sorry I didn't let you know earlier.

However, now that it is on the shelves, I will not back down, and my passion and love for the article will not change because of it.
