印刷术是中国古代的四大发明之一。中国古代汉族劳动人民经过长期实践和研究才发的。到了宋朝，雕版印刷事业发展到全盛时期。雕版印刷对文化的传播起了重大作用，但是也存在明显缺点∶第一，刻版费时费工费料，第二，大批书版存放不便，第三，有错字不容易更正。
Printing is one of the four great inventions in ancient China. It was only after long-term practice and research that the working people of Han nationality in ancient China developed it. In the Song Dynasty, engraving printing industry developed to its heyday. Block printing has played an important role in the spread of culture, but there are also obvious shortcomings: first, block printing takes time, labor and materials; second, a large number of books are inconvenient to store; third, it is not easy to correct the wrong words.

中国古代四大发明
Four great inventions in ancient China
毕升是北宋的一介布衣，现今湖北英山人。毕升初为印刷铺工人，专事手工印刷。他在印刷实践中，深知雕版印刷的艰难，认真总结前人的经验，发明了活字印刷术。
Bisheng is a Buyi of the Northern Song Dynasty. Now he is from Yingshan, Hubei Province. Bi Shengchu is a printer, specializing in manual printing. In the practice of printing, he knew the difficulty of block printing, summed up the experience of predecessors and invented movable type printing.
活字印刷术看似简单，但发明创造并非易事，且不说把雕版印刷改成活字印刷须独具匠心，仅就实际操作技术，如造字、排版等问题而言，流水槽模具 u型槽模具 电缆槽模具 隔离墩钢模具 护坡砖模具 钢制闸门 螺杆式启闭机 卷扬式启闭机也是一项巨大的工程。
Movable type printing seems to be simple, but it is not easy to invent and create. Not to mention that it requires originality to change engraving printing into movable type printing. In terms of practical operation technology, such as typesetting and typesetting, it is also a huge project.
