C1487 It's All in the Book

Thank you for your support for the first class and let this book go this far.

This book is my blood and sweat. I didn't expect it to be written until now, and I didn't expect it to have such good results.

All of this was given to me by you. Without saying anything else, all I can do is try my best to write a new book in the future.

This is the best way to repay you and myself
