Li Mo was originally a book editor who made a living. After traveling to Chang'an in the Tang Dynasty, he started by setting up a stall, copying books and annotating Buddhist scriptures. He invented movable type printing, modern typesetting, and binding technology, created a best-selling book industry chain, made friends with Li Bai, Du Fu, and Su Shi, and grew from an unknown scholar to a cultural giant. The core point of view is to see how modern publishing thinking can reduce the dimensionality and attack the ancient knowledge dissemination system, how to use books to leverage the court, reform the imperial examination, and enlighten the people's wisdom.
