Zheng Qian's full-text translation of practicing calligraphy

Zheng Qian was born in a poor family and could not afford to buy paper for practicing calligraphy. When living in Chang 'an, he learned that there were several rooms of persimmon leaves in Ji 'anji (where the Big Wild Goose Pagoda is located) in the south of the city, and moved to the temple to live. He uses persimmon leaves as paper every day and studies hard. He indulged in it, day after day, and never stopped. He even finished writing persimmon leaves in several rooms. Zheng Qian finally achieved great success, and his cursive script reached the state of "like a high wind sending clouds, gathering clouds to push the moon".
