This couplet was written by Gu Xiancheng, the leader of Lindong Party in Ming Dynasty ("Talking about the Interest of Honesty" 275). Gu founded Donglin Academy in Wuxi. After giving lectures, he often comments on state affairs. Later, people used it to advocate "saving the country and not forgetting to study", which still has positive significance. The first couplet combines the sound of reading with the sound of wind and rain, which is both poetic and meaningful. The bottom line is the ambition to rule the country and level the world. Wind to rain, home to country, ears to heart. Extremely neat, especially when used with words, such as the sound of books.

It is still of great significance today: scholars should not only read good books, but also care about national, political and world events and try their best to understand the world instead of reading dead books. So it should be posted on the school.
