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. Therefore, regardless of ancient and modern times, people always give the highest affirmation and special care to books. Hand-refined paper is especially suitable for China's calligraphy and painting, which can be divided into two kinds: raw and cooked. UNESCO defines a book as: any printed matter with more than 49 pages, excluding the front cover and back cover, published by a publishing house (enterprise), with a specific title and author's name and an international standard book number, is called a book. Books are works recorded on certain forms of materials with words or other information symbols for the purpose of spreading knowledge. Books are the product of human social practice, and they are a specific and developing tool for knowledge dissemination. In what we usually call picture books, pictures are no longer subservient to words, no longer dispensable, and even the life of picture books. Picture books tell a complete story with pictures and words, which is an ensemble of pictures and texts. To be more abstract, it is the art of telling stories through the interweaving and interaction of pictures and words at two different levels. Of course, there are exceptions, such as a wordless book without a word. Picture books should use pictures to speak, with great emphasis on the coherence of pictures. Usually within 32 or 40 pages, these dozens of pages should form a continuous visual image, just like a short film. The author of each picture book (more refers to the painter) is equivalent to a film director. He must tell a story clearly and beautifully in a limited space, which requires him not only to be good at using the lens language, but also to have the ability to grasp the visual rhythm. Therefore, a good picture book, even if a child can't read, should be able to read the general meaning as long as he "reads" the picture. In addition, generally speaking, picture books have well-designed layouts, from the cover and title page to the text and back cover, forming a complete whole; The left and right pages of words and pictures are interdependent; Pushing the story by turning pages ... It is also worth introducing that most people think that picture books are read by adults for children. [Edit this paragraph] Text+painting = picture book, and text × painting = picture book.
