Learning: refers to the content of the words in the book, not just the tangible components mixed in the book paper, ink and binding; It also refers to families with ancestors, scholarly families and scholarly generations; Reading atmosphere, study habits, etc.
From Song Jingxi's poem "Shu Huai Ci Chai Zhu Shu": "The book is scholarly and firm, and the old parents are empty."
Vernacular translation: the family background is scholarly and the industry is thin. Unfortunately, parents died young and became more and more dispersed.
The earliest origin of "Shuxiang" is said to be a plant named Cao Yun, whose fragrance can kill bookworms. Scholars who love books like life put Cao Yun in the book and called its fragrance "scholarly". The famous Tianyige Library is known as "the book without moths", which is said to be because there are weeds in every book.
Because of the affinity between rutting and books, other things related to weeds have become titles related to books. For example, the bookkeeper of an ancient school had a nice name: "Ruxiangli". Bai Juyi, a great poet, once served as this official. There is always grass in the library, and there are such sayings as "cloud window", "cloud department" and "cloud province" in the study.
For example, in the Tang Dynasty, Xu Jian's "Beginners" said: "If incense is made of paper fish, the book collection desk is also called Yuntai." These words all contain a hint of scholarly atmosphere, expressing people's admiration for scholarly style, cultural aesthetics and noble spirit.
