Zheng Banqiao was a painter and writer, and one of the "Eight Eccentrics of Yangzhou" in Qing Dynasty. He loved calligraphy since childhood and was determined to master the essence of ancient and modern calligraphy. He studied hard and practiced hard, but at first he just copied famous copybooks repeatedly and made little progress, which was deeply distressing. I didn't know until later that calligraphy was original and self-contained, and always copied other people's inscriptions. How can we do that? Since then, he has worked hard to innovate, explored the skills of painting bamboo in calligraphy art, and finally formed his own unique style-Banqiao style.
