During this period, the illustrations in the textbook caused a heated discussion. With the exposure of these illustrations, many illustrations have been exposed, especially the illustration in a children's picture book "Sweat", which is a popular science picture book, but the illustrations inside are very inappropriate. The illustration in this picture book shows two children licking the sweat of another child. This kind of illustration is really inappropriate. Sweat is a very popular picture book for children, suitable for children aged three to six. This picture book introduces how children sweat, but its content and illustrations are not suitable for children to watch. This picture book is published by Jiangsu Phoenix Children's Publishing House, and written by Zhang Xun, a teacher of Nanjing Art College. Now this picture book has also been taken off the shelf. Although it has been removed from the shelf, there are also great problems. These picture books should not be censored in the first place. As a picture book for children's popular science, the content should be simple and easy to understand, and the picture should be suitable for children of this age. However, the illustrations in this picture book are not suitable for children, and some text descriptions are particularly inappropriate. This picture book should not be reviewed at the beginning, because it may affect children's mental health and is not suitable for children to read. Now that all the books have been taken off the shelves, they won't be sold any more. During this period, a large number of problem material illustrations and picture book illustrations were exposed. These illustrations are really not suitable for children, and the content is not conducive to children's growth. As children's picture books and teaching materials, it should be more rigorous. After all, they are facing children, so we must carefully choose illustrations and pictures, and we must be particularly strict when reviewing them.
