Who was the inventor of the printing press?

According to Zhihu official website, John Gutenberg is German. He invented movable type printing and successfully invented the printing press by using this technology. The invention of the printing press greatly accelerated the production speed of books and reduced the cost of making books. Before Gutenberg, people usually used block printing, that is, printing by carving the whole text. However, this method is inefficient and costly. In contrast, movable type printing can greatly improve the printing speed and efficiency and reduce the production cost by using the combination of single letters. It caused a sensation at that time and provided important technical support for the Renaissance and religious reform in Europe. This invention also made books more popular and made an important contribution to the development of human civilization.
