Introduction to calligraphy and painting: Zheng Banqiao is unparalleled in poetry, calligraphy and painting. He was once the leading figure among the "Eight Eccentrics of Yangzhou" in the Qing Dynasty. The Zheng family has been studying for generations and can be described as a scholarly family. Ink bamboo has become the most important subject matter for Zheng Banqiao's paintings and poems. In his writing, bamboo also turned into a kind of character. The green bamboo is proud and unyielding, open-minded and strong, which can be said to be a reflection of Banqiao's noble temperament.
