3570 Wuyeesun           Discovered 1979 Dec. 14 at the Purple Mountain Observatory.
Named in honor of Wu Yeesun, a famous bonsai artist, who has been engaged in research on the art of bonsai for many years and who is regarded as a representative of the Lingnan School. His book Potted Landscape of Wennong, published in 1969, is the most highly regarded Chinese-English bilingual volume on the subject, and it has exerted a great influence in the bonsai art circles of the world.
