This sentence came from a poem in the Tang Dynasty poet Bai Juyi's "Fu De Gu Yuan Cao Farewell":"The flowers on the trees at the head of my family's inkstone washing pool bloom with faint ink marks." This sentence described an ancient pond and a tree with flowers blooming on the crown of the tree, as fresh as ink. The whole sentence meant that the flowers on the trees by the pond bloomed, and the faint ink traces disappeared with the flowers. This poem described the beauty and tranquility of nature, giving people a sense of comfort and peace.
