The following is not a brief introduction, but the author's complaints. Recently, I have not been in a good mood. Really, the collection has hardly moved, even if it is on the home page. I am very distressed about this. I don't know why, suddenly Think of a sentence, cherish everything you have. Cherish what you have, I understand. Old readers know how important collection is to the author. To be honest, there are only about 550 collections in this book. The reason for my distress is precisely This matter. But now I understand, I don’t ask for much data, I just hope that I can write it down without distraction, and I am worthy of the more than 500 people who have collected this book. My more than 500 brothers and sisters, thank you, have been giving me Encouragement. I don’t ask for anything else, I just hope that everyone can have a good mood after reading the book. May my dearest book friends be in good health. Ann, everything goes well and is safe.
