This is a couplet written by Fu Shan, a thinker, calligrapher and painter in the late Ming and early Qing Dynasties, an outstanding representative of Shanxi cultural celebrities and known as the "soul of Jin".

The antithetical couplets "Bamboo Rain, Pine Wind, Music Rhyme, Tea Smoke, Five Mountains and Book Sound" are six common and simple objects with harmonious and unified styles. They are all "good friends" of literati and writers, and also the author's favorite. The author's couplets are not composed from the other party's complex living environment, but are cleverly written from a small place, with a light and elegant image and six simple phrases that should be lonely, showing his peaceful and comfortable seclusion. Simple things, plain and faint style, can be skillfully used, which is exactly what the sentence says, simplicity is beauty! It's just a sketch of a famous landscape painting, falling and falling, and the bamboo rain is blowing gently. Under such circumstances, it is indeed a matter of infinite elegance and scenery to tune the piano, cook tea, read books and enjoy the moon. This couplet is not bad with any picture of mountains and rivers boiling tea. The author of this article is also used to discuss Yuntao Cave in Jinci, Taiyuan City, Shanxi Province.
