The content of the text has exceeded 60,000 words, and although the popularity is dismal, I haven't paid much attention to it. Now I don't rely on this to eat, so I can't sign it. About, whether it's on the shelves or not, it's not that important to me, and I didn't come here with the dream of making a fortune. As a newcomer, I just want to let more people see my work while learning, and slowly let more people recognize it. This is my first book, bits and pieces, and it took more than two years to prepare, which means I didn't do it on a whim. Regardless of whether you sign it or not. About, I will finish writing, the number of words in this book is expected to reach more than 7 million, please feel free to write it down - "deception"!
