Many experienced calligraphers pursue "book rhyme" too much, ignoring the popular beauty of the overall "book style". If you carefully observe those ugly books, you will find that their strokes and the organizational changes of the structure between strokes are very carefully arranged, which is by no means something a primary school student can do. But the rhyme is restrained and difficult to detect, and non-professionals can't see anything at a glance. Most non-professionals look at the beauty of a book from its style.
However, in the field of calligraphy, many calligraphers of ugly books are not as bad as people think, but their positions and aesthetic orientations are different, which makes many ordinary people unable to appreciate ugly books.
