What kind of calligraphy is the head of the book?

The head of the book is seal script. Seal script is a combination of ancient philology and calligraphy, and its strong decorative beauty can also make people enjoy irreplaceable classical beauty in modern social life. Seal script ranks first among the five books in China, namely seal script, official script, regular script, running script and cursive script, which fully illustrates its relationship with the other four books.
