Reflecting on the loss of Shen Kuo's "The Law of China's Survival" and the invention of movable type printing in Buyi Bi Sheng, the reasons why the working people and craftsmen in the Northern Song Dynasty were not paid attention to are as follows. If it is a history textbook to answer the question:

The ruling class in Song Dynasty did not attach importance to the invention and cultural communication of working people, so the spread of movable type printing was limited!

If you want to know the historical truth, why is movable type printing not widely spread?

1, China ancient books are very fixed. A movable type, printed once, must be removed and recast, while a piece of wood can be printed once and can be taken out and reprinted next time. China's ancient books pay attention to fixity. If you print more, you may make more mistakes. A piece of wood has been printed many times, and it is very economical for ancient bookstores to have mature technology to repair it when it is wrong or broken.

2, block printing, large characters can be carved, movable type printing must be literate, so the cost of movable type printing is naturally much higher than block printing.

3. The quality of block printing is very high, much higher than that of movable type printing! Moreover, movable type printing takes up more space than block printing, that is, the same paper, and the number of words printed by block printing is less, which is not economical enough! Copper movable type is particularly expensive!
