I believe that everyone is all too familiar on paper, because the need to use every day. However, the one before us a clean slate, we all know, do and how is it made of? Today, when I was a little guide for everyone who introduced.

This kind of paper on the reform and promotion of papermaking have much to contribute. Later, the continuous development of papermaking, another left-Bo paper, rattan paper, through continuous improvement, and finally became the white we are now common. After the above introduction I papermaking, we all have a certain understanding on paper, right? During this presentation, I realized the wisdom of the ancients, papermaking is one of the crystallization of their labor; the same time, I would like to remind you, paper hard-won, and we have to cherish to use it.
汉译：我相信，大家对纸是再熟悉不过了，因为每天都需要用到。可是，摆在我们面前的一张张白纸，大家都知道它是怎样做成的吗？今天我就当个小解说员，给大家介绍介绍。
相传，在公元前105元，蔡伦成功地发明了造纸术，他总结了前人造纸的经验，经过反复试验，用树皮、麻绳、破布、旧鱼网等原料经过挫、捣、抄、拱等72道工艺，终于做出了实用的纤维纸，当时称做“蔡侯纸”。这种纸对改革和推广造纸术有很大贡献。
后来，造纸术不断发展，又有了左伯纸、藤纸，经过不断改良，终于成了我们现在常见的白纸。
经过以上我对造纸术的介绍，大家都对纸有一定的了解了吧？在这段介绍中，我体会到了古人的智慧，造纸术也是他们的劳动结晶之一；同时，我还要提醒大家，纸来之不易，我们大家要好好珍惜使用它。
