Wang Xizhi, a calligrapher in the Eastern Jin Dynasty, is known as the "sage of calligraphy". He was born into a noble family in the Jin Dynasty, and the official was the right general. Wang Xizhi studied calligraphy with Mrs. Wei when he was a child, and later learned from others, forming his own family. His representative works include Huang Tingjing, Seventeen Posts, Sunny Posts in Fast Rain, etc. Wang Xizhi's story is Mo Chi. It is said that Wang Xizhi often writes in the pool, so he washes the inkstone in the pool. After a long time, the water in the pool was blackened by ink, which is the so-called "Mo Chi" and has been passed down to this day.
