This elegantly shaped Cizhou ware pillow, produced during the Jin dynasty, features a striking black-on-white painted design depicting geese among reeds and grasses rendered with fluid, expressive brushwork. The ruyi-shaped form reflects the refined aesthetic sensibilities of the period, while the dynamic naturalistic motifs exemplify the bold decorative tradition characteristic of Cizhou kilns. The piece bears the Zhangjiazao ("Made by the Zhang Family") mark, identifying it with one of the prominent workshop lineages associated with Cizhou production.
