Movable type printing was invented by Bi Sheng in Song Dynasty. Why is Kong Yiji written by Lu Xun still copying books for others?

One is that the Song Dynasty was rich in financial resources and adopted the policy of "storing wealth for the people". Private printing of books is very active, while the Qing Dynasty attached importance to agriculture and suppressed commerce, so its bourgeoisie always sprouted, which was also the pleasure of literary inquisition. Another reason is that after the Ming Dynasty, people became crazy because they worshipped Zhu Cheng's Neo-Confucianism too much, and of course there was the theory of mind and nature. This statement was very popular in the Ming and Qing dynasties, and there is a spirit in the text. A beggar who can't read words, even if he picks up a piece of paper with words written on it, will burn it to Wen Quxing at once. Printing will make the words worthless, so he will be rejected.
