Zhang Zhi, a great calligrapher in the Eastern Han Dynasty, studied calligraphy very hard when he was young. He practices calligraphy diligently every day, forgets to eat and sleep, writes a bald pen for a few days, and uses up several spindles of ink a month.
After writing every day, Zhang Zhi went to the pond in his backyard to wash his ink and ink stones. Over time, the pool turned black.
