Apologize + explain the situation during this time

To put it simply, my dad was hospitalized for surgery, and it took about ten days before and after the operation, because I had to accompany him, so I didn't have anything to say at the end of the month, I'm very sorry - bow.

In addition, not only is there no update at the end of the month, but before this matter is over, it is estimated that there is no way to add updates, so I'm really sorry - bow again.

I'll try to keep the update time as stable as I can, though.

By the way, the book will be on the shelves on the first day next month, and depending on the situation, I guess I don't have time to write a testimonial on the shelf, in short, I hope everyone can subscribe to this book, and let me stick to the matter of writing a book, thank you all - and bow again.

PS: I feel so unlucky lately...... (╥_╥)
