The mian tree bears fruit that resembles a chestnut. Furthermore, according to the Illustrated Classic of Materia Medica (Bencao Tujing) by Su Song, it is the eucommia tree. Its leaves are similar to those of the silkworm thorn tree, and when the bark is broken, white silk threads remain connected; in the region south of the Yangtze River, this is called mian.
