The implication of nine strings and pure ink

It means homesick. Nine strings means playing the piano, and seven ink means painting and calligraphy, as a medium for homesickness. From the ancient poem "Wen Qing Xu Ren Zhen in Liexian County" by Meng Jiao, a famous ancient poet. The author uses fu, pen and xing to describe and exaggerate his concern for home. I don't hesitate to write with chalk layer by layer to make my home lively and charming. The whole narrative process is like flowing water in one go, and every sentence is written without missing a word. Convincing.
