We often call those intellectual families scholarly, and now they are widely used, which can also refer to families with better family environment. But what is the origin of this title? Why is it called "shuxiangdi"?
It turns out that in order to prevent books from being damaged by beetles, the ancients usually put a few pieces of vanilla in them. This kind of herb is called Rutaceae. It is a perennial herb. It has a special clear fragrance. Even the withered fragrance will not fade. It can drive away the beetles. In ancient poetry, there is a description of "Rutaceae takes away the beetles". So the "fragrance" of "Book fragrance" refers to "rutile".
Because of the common inclusion of ruts in books, most of the words related to the word "Yun" are related to books. For example, 'Yun Bian' refers to books, 'Yun Pei' refers to book volumes, and 'Yun GE' refers to library. Even the national library is also named 'Yun Shu', and the collating Book responsible for collating books and correcting errors is called 'Yun Xiang Li'. Xu Jian of the Tang Dynasty's "preliminary study notes" said: 'Yun Xiang is a paper fish beetle, so the library is also called Yun Tai. 'these are from the rue.
But now it's hard to see the trace of Rutaceae. In order to prevent beetles, people often use camphor pills, sandalwood tablets and so on. For the literati who are good at imagination and nostalgia, the fragrance of books can only be a kind of inexhaustible historical memory and personal memory contained and accumulated in the volume.
