Books soaked in the flood can hardly be used normally, the words in the book may be illegible, and there will be some adhesion on the pages. Secondly, after the flood, books soaked in the flood may carry unknown germs, so it is impossible for us to take such books out and sell them in the market.

Despite the direct damage, our loss may be as high as 300 million yards. According to Zhao Nvshi, at present, three warehouses of China Library Network have been flooded, and warehouse 1 has more than 4 million books, so it is estimated that only a few of them can survive. As a website that mainly sells tail books, we lose not only money, but also those rare, out of print and old books that cannot be copied and printed.

The introduction of this book is as follows:

Books are called "the food for the soul", "the ladder of progress", "the key to wisdom" and "the kit of happiness". Books are the main tools used by human beings to record all their achievements, and also the important media for human beings to blend their feelings, acquire knowledge and inherit their experiences, which has made great contributions to the development of human civilization.

Tools for recording, analyzing, summarizing, organizing, discussing and explaining information, whether there are illustrations, hard copies or paperbacks, and whether there are envelopes, including preface, introduction, catalogue and index, are devices for increasing knowledge, deepening understanding, promoting and educating the human brain. The device needs visual or tactile form to exist and use.

Many great creations of mankind have gone through a long process of development, condensed the painstaking efforts of countless people, and are developing and growing all the time, and books are no exception. Take China as an example, it has a history of at least 3,500 years, during which people have invested more wisdom and labor.

Books have been created and improved repeatedly, and they have the appearance at this time. Generally speaking, in history, except some books made for special purposes, the development of books can be found in a little context.

In the earliest communication, people may only use gestures or volume as a medium when gesturing to each other. Later, from the accumulation of experience, some fixed syllables were determined to represent a certain meaning, so human beings walked out of the silent era and entered a society with words and no words.
