Statement

1. Tongtang is a new author. When he first wrote the book, he was ignorant and did not think seriously. He just wrote casually when he was inspired. Therefore, the first grade part is very willful.

2. Later, I was recommended by the editor and received support and encouragement from many warm-hearted people. I started to get serious about reading materials, constructing the overall situation, and thinking about details. When I was in the second grade, I gradually got started and tasted the recognition. Joy, and then became even more obsessed with writing.

In the third, third, and fourth grades, due to job changes, I entered a new field. I did the work of two people by myself. I had less writing time and slow updates. But I never had the thought of giving up. Even when I was physically and mentally exhausted from the busy work, I would persist in finishing the code. This is all because I have received more recognition from people, which gives me the motivation to keep persevering.

4. Finally, this book is my hard work. No matter what the final result is, I will never give up and complete it seriously.
