我国北宋时期,杭州一家印书作坊有一名印刷工人名叫毕昇。他对当时的雕版印刷方法不满,经过努力思考和多次试验,终于发明出“活字印刷术”,这就是我国著名的古代“四大发明”之一。事隔几千年,毕昇用他印刷的一本本书告诉后人,他的发明不仅仅是正确的、有用的,更是伟大的!因为,活字印刷为现代的印刷奠定了很好的基础,在世界印刷史上的价值更是无法估量。 During the Northern Song Dynasty in China, a printing workshop in Hangzhou called Bi Sheng. After dissatisfaction with the engraving printing method of the time, he finally invented the “movable type printing technique” through hard thinking and repeated experiments. This is one of the four famous inventions in ancient China. After a few thousand years, Bi Sheng used his printed book to tell his descendants that his invention was not only correct and useful but also great. Because movable type printing has laid a good foundation for modern printing Basis, in the history of the world printing is even more immeasurable value.
