What do you mean by "studying in the pool, the water in the pool is all black"?

Modern example: study hard.

Allusion: Wang Xizhi studied calligraphy since childhood. He worships Zhang Zhi, a great calligrapher in the Eastern Han Dynasty. As soon as he had time, he tried to figure out the shelf structure and momentum of the font, thinking that his fingers were painted on the skirt, and even the skirt was cut after a long time. Because of this, later generations called it "the sage of books".

Zhang Zhiyou is good at cursive writing. His academic spirit is very rigorous. His handwriting is different from ordinary people. He writes repeatedly on clothes and silk at home. After writing, he dyed and cut clothes. He insists on writing in the pool every day. Over time, the water in the pond turned black, so people called him "Cao Sheng".

Wang Xizhi is determined to catch up with Zhang Zhi. While traveling around the famous mountains and rivers of the motherland, he absorbed in studying the calligraphy of his predecessors and gradually formed his own unique style. After writing every day, he will go to the pond in front of his house to wash his pen and ink stone. Over time, the water in the pond turned black. People call this pond Mo Chi.

Later, people used this allusion to express their hard work. There is this person in Ceng Gong's Mo Chi Collection: "The taste of winter wheat yearns for Zhang Zhi, and the water in the pool is completely black. This is a sign of help. How can you believe in evil? "
