Friends, hello everyone, to say a word from the heart, it is not easy to write a book, you are persistent, I know that my book has such and such problems, I also know that it is difficult to reconcile, but I can only do it with my heart to write, I hope you give some encouragement, recommendation, collection, click, etc., as long as you move your precious little hands once, but it can make me happy for a few days without sleep, thank you.
