The last thoughts of this book will end today.

Without enthusiasm, locked in a small black room, I can't write a few words, and writing it tastes like chewing wax, so it can only be over.

I'm sorry, but I'm sorry to the more than 1,000 friends who subscribed to this book.

I also know that a word of sorry cannot be remedied, but it can only be said that way. (To be continued......)
