An illiterate book seller is a strange thing in the world. The books he sold made the ministers of the Tang Dynasty fight over the books. Emperor Taizong of the Tang Dynasty was also proud of getting a copy. He said: Reading Zhen Shufu's books is really comfortable!
Queen Changsun: Your Majesty and I want to marry our daughter to you! I just want your book as a betrothal gift!
What is even more exaggerated is that everyone in the Tang Dynasty bluntly said that getting a book from Zhen Shufu is better than worshiping gods and Buddhas and asking for blessings from Bodhisattvas.
Owning a Zhen Shufu schoolbag cures all diseases...
Although Zhen Shufu was known as illiterate, he became the first bookseller in the Tang Dynasty and was revered as the sage of calligraphy.
