我们今人办公如果要复印文件就可以直接用打印机或者复印机复印。可是古时候想要复印，就需要人们手抄或者雕版印刷了。直到了宋代，毕昇才发明了活字印刷术，大大提高了印刷的效率。
If we want to copy documents in the office today, we can directly use the printer or copier to make copies.But in ancient times, people needed to copy or block printing. It was not until the Song Dynasty that Bi Sheng invented movable type printing, which greatly improved the efficiency of printing.
活字印刷是先在胶泥上刻好字，然后做成同样体积大小的字块，经过处理后可以反复使用。印刷时选择合适的字方块，中间隔着竹子，再刷上墨，就可以印刷了。我国的活字印刷术已有八百多年的历史，已被世界教科文组织记入“急需保护的非物质文化遗产名录”。
Movable type printing is first carved on the clay, and then made into the same size of the block.After treatment they can be used again and again. When printing, select the appropriate word square, separated by bamboo, and then brush the ink, you can print.China's movable type printing has a history of more than 800 years and has been included in the list of intangible Cultural Heritage in Urgent need of protection by UNESCO.
现如今，孩子可以体验活字印刷的乐趣。比如我们选用唐诗《春晓》的活字模板，按照古诗中文字的先后顺序从右往左进行排列，因为排列好的字是反的，借助镜子进行检查，排列无误后，刷上墨汁，铺上宣纸，借助工具文字就印刷下来了。
Today, children can experience the joy of movable type printing. For example, we choose the movable character template of the Tang poem 《Spring Dawn》, and arrange the words in accordance with the order in the ancient poem from right to left.Because the arranged words are inverted,we can check the order with the help of a mirror, brush the ink after the arrangement is correct, spread the rice paper, and we can print down the words with the help of tools.
