The book is on the shelves, thank you for the help of the editors, thank you for your continued support, and thank you for every subscribing reader in the future! This book has been written for nearly half a year, and it is only now on the shelves, and it is obviously a flutter. In fact, I once had the idea of giving up, but I saw that there were still many friends who were supporting, every reward from them, every recommendation vote, and encouragement or suggestions in the book review area, plus the reluctance in the author's own heart, and finally persevered!

2015 has passed, a new year has arrived, and for me, it is also a new beginning! I will do my best to write this book well to repay everyone's support and love!

Finally, I wish you all a Happy New Year's Day! Happy family!
