A friend of mine took up bookbinding because his doctor ordered him to do something that would give him relaxation and activity without tension.我有个朋友学了书本装订，因为医生告诫他做些什么以获得放松和运动。
Bookbinding has its own characteristics, at work, when it violates the binding law of nature can not reach the necessary quality.图书装订有其自身的特点，在工作中如果违反装订规律，自然就达不到应有的质量。
