Zheng Xie (Chinese: 鄭燮 or 郑燮; 1693-1765), commonly known as Zheng Banqiao (Chinese: 鄭板橋 or 郑板桥), was a Chinese painter in Qing Dynasty. He expressed himself in art and became one of the Eight Eccentrics of Yangzhou. He was noted for his drawing of orchids, bamboo, and stones. In 1748 he briefly resumed an official career as "official calligrapher and painter" for the Qianlong Emperor.
