人们常常称信札为“尺牍”,又称为“函”,而且都以“封”作为量词和数词组合表示信件的多少。发行书籍又称为“出版”。你知道这是什么原因吗?在古代,用木片、竹片(也称竹简)做书写材料的时候,因为竹片宽度有限,不能写完自己所要表达的话,而木片可以在适当范围内随自己的需要决定它的宽度,所以往往采用木片做为书写材料。 People often refer to letter as “ruler”, also known as “letter”, and “seal” as a combination of quantifiers and nouns to express the number of letters. Published books, also known as “published.” Do you know why? In ancient times, when using wood chips and bamboo chips (also called bamboo slips) for writing materials, because the width of the bamboo chips was limited, they could not write what they wanted to express themselves. The chips could follow their own needs The need to determine its width, so often use wood as a writing material.
