Idioms and their stories
This idiom comes from The Water Margin: Song Taizong reads three volumes of Magnolia every day, and makes up for it in his spare time because he is missing something. Taste: "Opening books is beneficial, but it is not hard."
At the beginning of Song Dynasty, Song Taizong Zhao Guangyi ordered civil servant Liu Yun and others to compile a large-scale classified encyclopedia-Taiping General Category. This book is a valuable reference book, which collects and extracts the important contents of more than 600 kinds of ancient books, and classifies them into 55 books with the volume of 1000.
This book was compiled during the period of Xingguo in Song Taiping, so it was named Taiping General Category. For such a masterpiece, Song Taizong stipulated that at least two or three volumes should be read every day, and it should be finished within one year, so it was renamed Taiping Yu Lan. [ 1]
When Song Taizong made up his mind to spend energy reading this masterpiece, some people thought that the emperor had to deal with so many state affairs every day and it was too hard to read such a big book, so he was advised to read less and not read every day to avoid overwork. However, Song Taizong replied, "I like reading very much. I often get pleasure from books. Reading more books is always beneficial. Besides, I don't feel tired. " So, he still insists on reading three volumes every day. Sometimes he has to make up for the time lost because of the busy state affairs, and often says to people around him, "As long as you open the book, it is always good."
Song Taizong is very learned, because he reads three volumes of Taiping Yu Lan every day, and he is also very handy in handling state affairs. At that time, ministers saw that the emperor was so diligent in reading and followed suit, so the atmosphere of reading was very prosperous at that time. Prime Minister Pu often does not study, but tirelessly reads The Analects, which is called "Half Analects of Confucius governs the world".
Later, "opening a book is beneficial" became an idiom, describing that it is always beneficial to open a book to read. It is often used to encourage people to study hard and reading more books will benefit them.
Used in "not seeking a very solution" [ 1]
