Zheng Xie (1693-1765), courtesy name Kerou and pseudonym Banqiao, was a native of Xinghua, Jiangsu. Zheng Banqiao was educated at home from a young age. He left home to study in Zhenzhou when he was 17 years old. Banqiao had gatherings with Wang Shishen and other artists. As their style of paintings was very different from the conventional painting styles of the time, they often viewed as "eccentric painters". Collectively, they were referred to as the Eight Eccentrics of Yangzhou.
Zheng Banqiao was noted for his paintings of orchids, bamboo and stones. He also painted pine trees, plum blossoms, chrysanthemums and other plants.
Zheng maintained that one should not be confined to traditional ways of painting, but should learn from nature. Once one had fully mastered his skill, he would be able to freely express his true emotions in his paintings. Banqiao put forward a theary of three stages of painting which required that the painter fully master the bamboo in his eyes, hands and heart, combining careful deliberation with skillful techniques.
Zheng Banqiao died in 1765 at the age of 73.
